Question

The vertex of this parabola is at (-3,-2). Which of the following could be its equation?

Answer 1

B x = -2(y+2)^2 -3

Explanation:

The vertex form of a sideways parabola is

x = a(y-k)^2+h where (h,k) is the vertex and a is a constant

x = a(y--2)^2 -3

x = a(y+2)^2 -3

B is the only option with +2 and -3in the proper postion

x = -2(y+2)^2 -3
