Answer 2

Do you know the vertex formula?

Answer 3

isnt it y=a(x-h)^2 +k?

Answer 4

\[\LARGE -\frac{b}{2a}\]

Answer 5

\[\LARGE y=ax^2+bx+c\]

Answer 6

That will give you the x-coordinate, just plug that back in to find the y-coordinate.

Answer 7

what? do the -b/2a to find the x then plug it into the y=ax^2 +bx+c ?

Answer 8

Yup, so find the x-coordinate.

Answer 9

so it would look like this? and the answer would be 6?
