In this equation:
\[y=(x-0)^2+0\]
OpenStudy (mertsj):
The vertex is (0,0)

It's in vertex form.
2(x-h)^2+3
Your vertex would be h,3
OpenStudy (dtan5457):
So what you can tell from here is that the y coordinate must be 3 for the vertex of your graphs
OpenStudy (mertsj):
In this equation:
\[y=(x-3)^2+6\]
OpenStudy (mertsj):
the vertex is moved 3 to the right and 6 up
OpenStudy (mertsj):
So in your example, the vertex is moved h units to the right and 3 units up. The means your choices are a or d

a?
OpenStudy (dtan5457):
It's both A and D.
OpenStudy (dtan5457):
They both have the correct y coordinate of the vertex (3), which is all that matters
OpenStudy (anonymous):
it cant be both
OpenStudy (anonymous):
wont let me pick two

i believe it would be D, which is the best possible answer..
OpenStudy (mertsj):
It is not both. Because of the 2 in front of the parentheses, the parabola is "skinnier" than normal. That would be d
OpenStudy (dtan5457):
Oh, I see it now. That makes sense.
OpenStudy (anonymous):
so its D thank u
