What is the vertex of g(x) = –3x2 + 18x + 2?

(3, –25)
(–3, –25)
(3, 29)
(–3, 29)

The vertex would be D) (-3, 29)

Step-by-step explanation:

To find the vertex , start by find the x-value. For this we can use the equation below.

x = -b/2a

In which a is the coefficient of x^2 and b is the coefficient of x.

x = -b/2a

x = -(18)/2(-3)

x = -18/-6

x = 3

Now that we have x, we find y by plugging 3 in for each x.

g(x) = -3x^2 + 18x + 2

g(x) = -3(3)^2 + 18(3) + 2

g(x) = -3(9) + 18(3) + 2

g(x) = -27 + 54 + 2

g(x) = 29

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
