The vertex of a parabola is (−5,2) , and its focus is (−5,6) .

what is the standard form of the parabola?

?

Step-by-step explanation:

If you plot the focus and the vertex, you see that the focus is on the same vertical line, just 4 units up.  Since the vertex is below the focus and a parabola ALWAYS wraps around the focus, the parabola is a positive y equals x-squared type.  Depending upon what you call standard form will dictate how your answer "looks", although they are both the same parabola.  There are 2 forms:

and

We will work on the first one, then rewrite it into the second one.

Our h value is -5, our k value is 2 (from the vertex (h,k)), and p is defined as the distance between the focus and the vertex.  Our p is 4.  Filling all that in:

That's one form.  If we expand the left side of that form we have

 Now divide both sides by 16 to get

Now add 2 to both sides in the form 32/16 to get

They are both the same parabola; pick whichever one fits your needs.
