Question

The function f(x) = 7 – 4x + x2 written in vertex form is f(x) = (x – 2)2 + 3. What is the axis of symmetry for the function? X = –3 x = –2 x = 2 x = 3

Answer 1

x = 2

Explanation:

took the test on edge

Answer 2

x = 2

Explanation:

The vertex form tells you the vertex is (x, y) = (2, 3). The vertical line through the vertex, x=2, is the axis of symmetry.
