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
x = -y^2-6y-9
And solve for y:
x + 9 = -y^2-6y
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.
