Go back to the general formula for a parabola which is

The formula for the x-coordinate of the vertex is
With the parabola ,

So,
and

So, the vertex of this parabola is (0,0). You are asked to keep the
shape the same, but move the vertex to (-3,2)
I can say
I don't want to change, because that would change the shape, so

So far, I have
I can use (-3,2) to find

answer
I'll plot both these equations

Each vertex looks OK
