Decomposing Functions Using Composition of Functions

Compositions of Functions (More Challenging) examples where we work backwards to find two functions that compose together to find a third function in this free math video tutorial by Mario's Math Tutoring.

0:20 Overview of How to Work With Composition of Functions
0:43 Introductory Example f(x)=2x-1, g(x)=x^2
0:56 Find f(g(3))
1:29 Find g(f(3))
2:08 Find g(f(x))
2:32 Find f(g(x))
2:57 Example 1 Find 2 Functions when Composed is h(x)=Square Root(2x-3) More Than 1 Answer
4:24 Example 2 Find 2 Functions when Composed is h(x)=1/((3(9x-7)^2)
