Learn how to compute the value of composite functions.
 What is (f o g)(2) if f(x) = x^2  3x + 5, g(x) = 4x + 1, and h(x) = square root of x?
 What is (h o g)(2) if f(x) = x^2  3x + 5, g(x) = 4x + 1, and h(x) = square root of x?
 What is (g o f)(4) if f(x) = x^2  3x + 5, g(x) = 4x + 1, and h(x) = square root of x?
 What is (h o f)(5) if f(x) = x^2  3x + 5, g(x) = 4x + 1, and h(x) = square root of x?

 How do you compute the value of composite functions?
 How do you know which function to compute first in a composite function?
This lesson shows how to do some computations with composite functions. Five different problems are shown using the same 3 functions and evaluating the composite of the functions in different orders. This is a great composite function tutorial with some very complete examples.
