Question

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

equation?
(-3,-2)
O A. y=-2(x-3)2 + 2
O B. y=-2(x+3)2 + 2
O C. y=-2(x-3)2-2
O D. y=-2(x+3)2 - 2

Answer 1

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

Explanation:

The vertex is (h,k )

h = -3

k= -2

These equations are in vertex form.

Vertex form: y= a(x-h)^2 + k

so,

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

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

Answer 2

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