Advanced Math practice question

Answer: -2

At x = 0, 12a = 6 gives a = 1/2. The vertex is midway between the zeros, at x = 4, where y = (1/2)(2)(−2) = −2.

Common wrong answers

If you answered 2

2 has the sign wrong.

If you answered 4

4 is the x-coordinate of the vertex.

If you answered -4

−4 uses a = 1.
