The vertex of this parabola is at (-2, 5) (opens upward)

which of the following could be its equation?

a.) y=3(x+2)^2-5
b.) y=3(x+2)^2+5
c.) y=3(x-2)^2+5
d.) y=3(x-2)^2-5

Respuesta :

Answer:

b.  y = 3(x+2)^2 + 5

Step-by-step explanation:

The vertex form of a parabola is

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

Here  h = -2 and k = 5 so the following could be the required equation\;

y = 3(x+2)^2 + 5
