I am given f(x)=(x-3)^2 on the limited domain of [3,infinity)
My objective is to find the inverse function and domain...
I am able to find f^-1(x) = 3+\sqrt{x} no problem
But how do I find the domain? I thought it was [3,infinity] but that's not the right answer. So I tried (-infinity,3] and that was no good. What am I supposed to put in here? (help me find the ordered pair please ^^)
