Question

Which equation has a graph that is a parabola with a vertex at (-2, 0)?

0 y=-2x18
y = (x + 2)2
y = (x - 2)2
0 y=x2-2

Answer 1

Hey there!

The graph is shifting 2 units to the left, and we know this because the -2 represents the direction in which the graph would shift.

So, our answer is best shown by y = (x+2)2

Answer 2

Explanation:

y=(x+2)2 because when x= -2 the result is 0
