Given:

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

Required:

Find the equation of the parabola.

Explanation:

The equation of the parabola in vertex form is:

[tex]y=a(x-h)^2+k[/tex]

We can observe from the options that the value of a = 3 and vertex (h,k) is given (-2,5).

So the equation of the parabola will be:

[tex]y=3(x+2)^2+5[/tex]
