How do find the inverse function for this problem:
f(x) = (x+3)^2, x is greater or less than 3
I know the first thing you do is switch the variables, so it looks like this:
x = (y+3)^2
Then expand:
x = y^26y9
And solve for y:
x + 9 = y^26y
I get a little confused after that with y. Help please? Thank you very much!

oh, i also meant that x is greater than or equal to 3. sorry.
