Question

What is the vertex for the function? (You will want to find the axis of symmetry first.) Write as an ordered pair, leaving no spaces, such as (1,-4).

y = -3x2 + 6x

Answer 1

The axis of symmetry for a quadratic function is at x=-b/2a. In this case x=-6/-6=1
Substitute x=1 into the function to find the vertex.

Answer 2

I think the vertex is close to (1,3).

Answer 3

Got that?
