Question

A coordinate plane shows a parabola that opens downward with a plotted point. Both axes range from negative 8 to 8 in increments of 2. this is the image.

What is the vertex form of the graphed equation?

(1 point)
y=−2
(x−
)2+

Answer 1

I don't have the actual image. To fill the blanks you need the vertex (h,k) from the graph — the vertex is the highest point because the parabola opens downward. The equation is

y = −2(x − h)^2 + k.

Read h and k from the grid (each tick = 2 units). For example, if the vertex is at (1, 6) the vertex form would be

y = −2(x − 1)^2 + 6.

Tell me the vertex coordinates (or upload the image) and I will fill in the blanks exactly.
