What is the vertex form of the graphed equation?

(1 point)
y=−2
(x−
)2+

Answer 1

I can’t read the graph from your message. Please either upload the image or tell me the vertex coordinates (h,k) shown on the graph (and one other plotted point on the parabola if you want me to check).

How to get the answer once you have the vertex:
- Vertex form is y = a(x − h)^2 + k. Here a = −2, so y = −2(x − h)^2 + k.
- Read the vertex off the graph as (h,k) and substitute those values into the blanks.
- Optionally verify by plugging in another plotted point (x,y) to make sure the equation matches.

Example: if the vertex is (1,4), the equation is y = −2(x − 1)^2 + 4.

Send the vertex (or the image) and I’ll fill in the blanks exactly.
