Question

Use the vertex form to write the equation of the parabola.

Answer 1

click "AttachFile" below this textbox

Answer 2

What if the picture is only a screenshot?

Answer 3

That is not a very good graph but the points are the same on the original.

Answer 4

that looks good :)
so what do you know about `vertex form` of a parabola ?

Answer 5

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

vertex = (h,k)

Answer 6

and distance from focus to directrix is (1/4|a|)

Answer 7

but how do you find the focus and the directrix?

Answer 8

sorry was afk @jaredb2000 still here ? :)

Answer 9

Since A = (-2, 2) is vertex,
h = -2
k = 2

so the required equation would be : y = a(x+2)^2 + 2

Answer 10

plugin any other given point to find the value of "a"

Answer 11

ok thanks :)

Answer 12

np :) are you able to solve "a" ?
