Question

Which of the following equations is of a parabola with a vertex at (0, 3)?

Answer 1

"Which of the following equations" means there are choices, right?

Answer 2

ya

Answer 3

For a parabola having vertex at (h,k), it should be like this:
y = a(x-h)^2+k
If not, then expand it/make the equation into this form.

Answer 4

idk tbh

Answer 5

y=\[\left( x -3 \right)^{2}\]

Answer 6

@goformit100 will u help me

Answer 7

No, sorry Sir

Answer 8

o cool message me

Answer 11

@Callisto

Answer 12

"For a parabola having vertex at (h,k), it should be like this:
y = a(x-h)^2+k"

Can you identify what h and k are?

Answer 13

I posted what I thought the answer is am I right

Answer 14

It is not correct.

Answer 15

okay will u explain it

Answer 16

y = x^2- 3
is this the answer @Callisto

Answer 17

Since we have (0,3) as the vertex. Compared with (h,k), we can identify that h=0, k=3
Put (h,k) into y=a(x-k)^2+k,
What would you get?

Answer 18

Y=x^2+3

Answer 19

That's it.
