Question

6.

Identify the axis of symmetry of the parabola.



A. y = 1

B. x = 1

C. y = −1

D. x = −1

Answer 1

D. x = −1

Explanation:

In the graph, the vertex of the parabola hits point (-1,-2). Therefore, the axis of symmetry is x = -1. It is not y = -2, since the parabola opens vertically, not horizontally.
