Respuesta :

vertex form of a parabola

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

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

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

Choice B

Answer:

The answer is B.

Step-by-step explanation:

When you have an equation in vertex form, we can find the x value of the vertex by looking in the parenthesis. The opposite number as is being added to x is the x value. Since we are looking for -3, we are looking for a positive 3 in the parenthesis. This leaves us with just A and B.

On the outside, the constant is the y value of the vertex. Since we are looking for a positive 2, we know B is the correct choice.
