hello

am stopped at this problem -_-

let where x>2

Find a formula for the inverse function of it, if exists.

My solution:

f`(x)=4x-..... so f is increas..so its 1-1funct..so inverse is exist.

its easy to prove that the inverse function is exist..=)

But the problem is finding the inverse function

ok let ..

how to find the x in terms of y !!

i tried to get the natural logarthmic of both sides but it failed :S

any help?!
