http://www.freemathvideos.com In this video tutorial I show how to take two functions, f(x) and g(x) and prove that they are inverse functions. I do this by taking the function f(x), and finding the inverse of the function g(x). I then show that if the two functions are inverses, f(g(x)) = g(f(x)) = x.
f(x) = 7x + 1 , f'(x) = x + 5
