Question

The axis of symmetry for the function f(x) = –2x2 + 4x + 1 is the line x = 1. Where is the vertex of the function located? (0, 1) (1, 3) (1, 7) (2, 1)

Answer 1

Answer:

Step-by-step explanation:

If the axis of symmetry is located at x = 1, that is the h value of our vertex (h, k).  If we know h, all we have to do to find k is sub the value for h into the quadratic and evaluate.

$f(1)=-2(1)^2+4(1)+1$

so f(1) = 3.  Your choice is (1, 3)
