Function of a Function
Hello! In this video, I will go over another practice problem that is almost guaranteed to show up on your standardized math tests. You will need to understand functions. Check out this video if you haven't already seen it. https://rumble.com/vlv8vf-finding-domain-of-functions-how-to-examples-caveman-chang.html
For example, if you are given f(x) = x+1; x=2 then the answer would be 3 because 2+1 = 3. That's a simple example of how a function works. For this video, we go over the function of a function. Instead of being given the value of variable x, you take the f(x) and assign it as the new x.
Problem for this video: f(f(x)) = ? given f(x) = x+(1/x)
Depending on how the exam is written, this might be a very short problem or you may need to manipulate the equation into a form that fits the multiple choice options.
Let's jump right in! Let me know in the comments if you have any questions.
