C is the answer? in the comment

no

someone help

OpenStudy (mertsj):

In this equation: \[y=(x-0)^2+0\]

OpenStudy (mertsj):

The vertex is (0,0)

OpenStudy (dtan5457):

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

OpenStudy (anonymous):

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 @Directrix

OpenStudy (anonymous):

@TheSmartOne

OpenStudy (anonymous):

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
