Question

Which of these equations represent this graph?

A. y = -2(x - 1)^2
B. y = -2(x + 1)^2 + 6
C. y = -2(x - 1)^2 + 6
D. y = 2(x - 1)^2

Answer 1

The equations are in completing the square form
a(x+d)^2+e=0
So the vertex would be -d, e

Answer 2

The answer would be C

Answer 3

negative because it opens down
(x^2 -1) shifts it right
+6 shifts up 6
C

Answer 4

Ahh thanks. I was thinking it was B or C but wasn't sure. Thanks a lot!
