I have a question I'm stuck on: Find two functions such that f(x)= f-1(x). (For all x in domain of f) It's not f minus 1. I don't know how to type the Value of Inverse of f at x. An assistance would be greatly appreciated!

Huu hello ! What about y=x and y=-x ?

Question 1 a. of this thread is relevant: http://www.mathhelpforum.com/math-he...questions.html See if you can place conditions on a, b, c and d so that the function is its own inverse.

Originally Posted by Maga22 Thanks. So it seemed easy. These are two functions such that f(x) = the value of inverse of f at x? Well, for the second one, f(x) = -x, find the inverse function. Let y = f(x) = -x. Now, switch the roles of y and x: Now solve for y: . This is your inverse function. So You do the one for y = x. -Dan
