Question

Which parabola(s) have an axis of symmetry of x = -1

Answer 1

2 Answers: Choice B and C

Step-by-step explanation:

Notice how the vertical line through the center of these parabolas is at x = -1. In other words, the vertical line cuts through -1 on the x axis. Reflecting one half of the parabola over this line will result in the other half.

Answer 2

b,c

Step-by-step explanation:

The axis of symmetry is along the vertex

a has a vertex at x=1

b has a vertex at x = -1

c has a vertex at x=-1

d has a vertex at x =2
