Question

Please help me. 30 pointss

Answer 1

Explanation:

This is a dome shaped parabola (because the coefficient of x^2 is negative)

max occurs at x = -b/2a where b = 0 and a = - 3

so max occurs at x = 0

plug in x = 0 to find out what that max is

max = 12

Answer 2

Answer: Does, 12, 0

Explanation:

Because the function has a - in front it is facing downwards which means there is a max at the vertex

To find the vertex you can use x=-b/2a There is no b so x=0 plug that into equation:

y=-3(0)²+12 y=12 So at (0,12) there is a max

To fill in blanks

does

12
