1. The problem statement, all variables and given/known data I'm trying to find the vertex of this parabola: y^2-12=12x 3. The attempt at a solution Initially I tried to take the derivative and find the vertex by finding where it the function is zero, but apparently that does not work in this situation. Is it because it is not in standard form? I've been staring at this problem for hours. I need a hint. Thanks.
