Find the Domain of (F/G) when F(X) = X² - 25 and G(X) = X - 5: An Essential Guide
Find the domain of (F/G)(X) where F(X)=X²-25 and G(X)=X-5. Get the answer in this short and simple guide.
If you thought math was boring, think again! The world of numbers and equations can actually be quite entertaining, especially when you discover the quirky patterns and unexpected results that lie beneath the surface. Take, for instance, the function F(x) = x^2 – 25 and G(x) = x – 5. These seemingly innocent formulas may not look like much at first glance, but when you put them together and ask about the domain of (F/G)(x), things start to get interesting.
Before we dive into the nitty-gritty of this mathematical conundrum, let's take a step back and make sure we're all on the same page. When we talk about the domain of a function, we're referring to the set of all possible input values that the function can take. In other words, it's the range of numbers that you're allowed to plug into the formula without breaking any rules or causing the function to blow up into infinity or negative infinity.
So, with that in mind, let's return to our original question: what is the domain of (F/G)(x)? To answer this, we need to do a bit of algebraic manipulation to simplify the expression. Specifically, we need to divide F(x) by G(x) and see what happens:
(F/G)(x) = (x^2 – 25)/(x – 5)
Now, if you're feeling confident in your math skills, you might be tempted to jump straight to the answer and say that the domain of this function is all real numbers except x=5. After all, dividing by zero is a big no-no in math, and if we plug in x=5, we get a denominator of zero, which means the whole expression blows up.
However, as any good mathematician knows, we can't just assume that our answer is correct without proving it rigorously. So, let's take a closer look at what's going on when we divide F(x) by G(x).
One way to approach this problem is to use long division, just like you learned in elementary school. If we write out the division step-by-step, we get:
x + 5 | x^2 – 25
-x^2 – 5x
------------
5x – 25
5x + 25
--------
-50
As you can see, we end up with a quotient of x + 5 and a remainder of -50. This means that:
(F/G)(x) = x + 5 – 50/(x – 5)
Now, the question is: what is the domain of this new expression? We already know that x=5 is not allowed, since that would make the denominator zero. But what about other values of x?
One thing to note is that the first term, x + 5, is defined for all real numbers. So, we only need to worry about the second term, -50/(x – 5). To figure out where this term is defined, we need to think about what happens as x gets close to 5 from either side.
Let's start with x slightly less than 5. In this case, x – 5 is negative, so -50/(x – 5) is negative as well. As x gets closer and closer to 5, the denominator becomes smaller and smaller, which means the fraction becomes larger and larger in absolute value. So, as x approaches 5 from the left, -50/(x – 5) approaches negative infinity.
On the other hand, if we take x slightly greater than 5, then x – 5 is positive, so -50/(x – 5) is negative again. As x gets closer to 5 from the right, the denominator becomes smaller and smaller, which means the fraction becomes larger and larger in absolute value (just like before). So, as x approaches 5 from the right, -50/(x – 5) approaches positive infinity.
Putting these two observations together, we can conclude that the only value of x that is not allowed in the expression (F/G)(x) is x=5. For all other values of x, the expression is defined and finite. Therefore, the domain of (F/G)(x) is all real numbers except x=5.
Now, you may be wondering: what's the point of all this math? Why do we care about the domain of (F/G)(x)? Well, for one thing, understanding the domain of a function is crucial if you want to graph it or analyze its behavior in various contexts. It also helps you avoid making careless mistakes in calculations and ensures that you don't accidentally break any mathematical laws.
But beyond all that, there's something inherently fascinating about exploring the hidden patterns and secrets of the mathematical universe. Even a simple question like the domain of (F/G)(x) can lead us on a journey of discovery and wonder, uncovering new insights and connections along the way.
So, the next time you encounter a seemingly boring math problem, remember: there's always more than meets the eye. With a little creativity and curiosity, you too can unlock the mysteries of the mathematical world and find joy in the beauty of numbers.
The Dreaded Math Problem
Alright, let's face it. Math can be scary. All those numbers and letters mixed together in seemingly random equations can send shivers down anyone's spine. But fear not, my friends! We're going to tackle a tricky math problem today and have a little fun while doing it.
The Problem at Hand
So, the problem we're dealing with is this: If F(X) = X2 – 25 And G(X) = X – 5, What Is The Domain Of (Startfraction F Over G Endfraction) (X)?
Oh boy, that looks complicated. But let's break it down into smaller parts and see what we're really dealing with here.
Breaking Down the Equation
First, we have F(X) = X2 – 25. This simply means that we're taking the value of X, squaring it, and then subtracting 25 from it. Easy peasy, right?
Next up is G(X) = X – 5. This one's even simpler. We're just taking the value of X and subtracting 5 from it.
Now, here's where things get a little trickier. We're asked to find the domain of (Startfraction F Over G Endfraction) (X). What does that even mean?
The Meaning of Domain
For those of you who aren't math whizzes, let me explain what domain means. It's basically the set of all possible values that a function can take. In simpler terms, it's the range of numbers that will work in our equation without causing any problems.
So, when we're asked to find the domain of (Startfraction F Over G Endfraction) (X), we're really just looking for the range of values that X can take without breaking the equation.
Putting it All Together
Now that we know what we're dealing with, let's put all the pieces together and solve this thing.
(Startfraction F Over G Endfraction) (X) simply means that we're taking the fraction of F(X) over G(X). In other words:
(Startfraction F Over G Endfraction) (X) = (X2 – 25)/(X – 5)
Now, we need to find the domain of this equation. That means we need to figure out what values of X will work without causing any problems.
The Problematic Values of X
So, what values of X could cause problems in this equation? Well, if we look at the denominator (X – 5), we can see that if X = 5, we'll be dividing by zero. And as we all know, dividing by zero is a big no-no in math.
So, X = 5 is definitely out. But are there any other values we need to worry about?
Finding the Domain
To find the domain of our equation, we need to exclude any values of X that would cause problems. So, we know that X cannot equal 5. But what about all the other values?
Well, luckily for us, there aren't any other values that would cause problems. We can plug in any other number for X and our equation will work just fine.
So, the domain of (Startfraction F Over G Endfraction) (X) is all real numbers except for 5.
Conclusion
And there you have it, folks! We've solved the dreaded math problem and found the domain of (Startfraction F Over G Endfraction) (X). Wasn't that fun?
