Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). The vertex of a parabola is (-2, -20), and its y-intercept is (0, -12).
The equation of the parabola is y =
x2 +
x +
.

Step-by-step explanation:

Hello, we know that if the equation is

Then the vertex is the the point (h,k)

Here, the vertex is the point (-2,-20) so we can write, a being a real number that we will have to find,

On the other hand, we know that the y-intercept is (0,-12) so we can write

So the equation becomes.

And we can give the standard form as below.

Thank you.
