Compositions of Functions

Functions can be combined into a composition of functions. In a composition, one function is performed on a value, then the output of the first function is fed into a second.

Let's find FoG(x) of two example equations:

Figure 1.

Now, let's find GoF(x) of the same two example equations:

Figure 2.

How would we find GoF(2)?
