**Bryan**, Tuesday, July 1, 2008 at 10:54pmOk. An inverse function is formed from switch in the input and output variables(x,y).

so y = 3x -1

flip x = 3y-1 and solve for y again

x+1=3y

y = 1/3(x+1)

so f^-1(x) = 1/3(x+1)

and the inverse of an inverse function is the original equation: f(x) = 3x-1
