Question

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

A. y = x2
B. y = 2x2 + 3
C. y = (x + 2)2 + 3
D. y = (x - 2)2 + 3

Answer 1

I think my answe is D but im not sure

Answer 2

Could you try to be sure? You know the vertex for of a parabola/

Answer 3

vertex form*

Answer 4

wait no thats wrong ,it'sC!

Answer 5

Is that your final answer?

Answer 6

yup

Answer 7

Okay, that's correct :)
Vertex form of a parabola would be
\[\Large y = a(x - \color{red}h)^2 + \color{blue}k\]

Where \((\color{red}h,\color{blue}k)\) is the vertex :)
