In this video you will be shown how to find the composite function ff(x). This means you need to put the function f into itself. So in example 1 the function f(x) is 5x+1 and you are asked to work out the function ff(x). To do this substitute x in one function to (5x+1), so ff(x) = 5(5x+1)+1. If you expand and simplify you get the final ...

In today's video, we're going over composite functions - what they are, how they're written, and how to solve them! In short, a composition of functions is created when one function is used as the input for another. Sometimes, you'll be given an actual input value, which would first be solved in the interior function. Then, that output becomes ...
