Can anyone explain the composition of functions, in a simple, easily understood way?
Alright, so I’m taking Precalculus right now, and we are supposed to teach ourselves how to understand the composition of functions. The only thing I know is f(g(x)). But I don’t know how to apply it to a problem. I know the first step is to set f=g(x). But that’s all I know. I was wondering could anyone possibly explain how to do this, in an easily understood way?
Thanks.

Composition of functions means you are given two functions and a starting value. First you do one function using the starting value. Then you do the second function using the answer you got from the first function.
Say f(x) = 2x and g(x ) = x + 3
f(g(8)) is f(11) = 22
g(f(8) is g(16) = 19
