Question

5.

Identify the axis of symmetry of the parabola.



A. y = −1

B. x = −1

C. x = 1

D. y = 1

Answer 1

B. 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.

Answer 2

Answer is C x=1 because that’s the middle of it.
