what do you think?

Answer 2

the -1 just means, is going downwards

Answer 3

This equation is in vertex form, you can find the vertex just by looking at the equation

Answer 4

Oh I see, so the vertex is (2, 3) ?

Answer 5

vertex form is a(x-h)^2+k, where the vertex is at the point (h,k)
your h is 2 and your k is 3. Now what's the vertex?

Answer 6
