Question

What is the vertex form of the equation?

y = -x^2 + 12x - 4

Answer 1

The vertex form of a quadratic is of the format:

y = a*(x-h)^2 + k where (h,k) is the vertex of the parabola. "a" is a constant which we have to figure out to solve this problem.

Answer 2

So I have to graph something for this problem?

Answer 3

Sorry, I'm not good at these kinds of problems.

Answer 4

I think we're going to have to complete the square technique on the given equation to get the vertex form.

Answer 5

y = -x^2 + 12x - 4

y = - ( x^2 - 12x + __?__) - 4 + __?__
