Question

Identify the vertex for the graph of y = −2x2 − 12x + 5.

Answer 1

vertex:
y = −2x^2 − 12x + 5
y = −4x − 12

set it to zero

0=-4x-12
12=-4x
-3=x

Answer 2

You vertex will be
(-3,y)

plug -3 to the original equation and you got yourself a y

Answer 3

need more help?

Answer 4

I take that as a yes ok then

when x=-3
y=23

vertex is then
(-3,23)

Answer 5

THANK YOU SO MUCH!!! :)
