Question

When graphed which equation will yield the same maximum value as the graph of y = -3x^2 + 6x + 9 ?

a) y = -3(x - 1)^2+12
b) y = -3(x + 1) ^2 - 12
c) y = 3(x - 1)^2 -12
d) y = 3(x + 1)^2 + 12

Answer 1

-3(x - 1)^2+12

Explanation:

Have a good day :)

Answer 2

A

Explanation:

Graphed below are all 5 graphs. The one in red is the original, but it cannot be seen because it is entirely concealed by the blue graph, or graph A. Since they are the same graph, they must share all characteristics, including a maximum value. Therefore, the correct answer is choice A. Hope this helps!
