Composition Functions

*A composite function is when you have two functions and the y values of the first function becomes the x value of the second function. To use composite functions, you put them through a function machine. . The composite of the function is ”g of f of x” or g(f(x)).*
This is an example of a function machine. If you put an "X" through the first machine, and it comes out of the second machine as an "X" then it's verfied that the two functions are composition functions.
