Answer:

vertex=?

Explanation:

given data:

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

  • find values of a,b,c:

from the given equation

a=-3,b=18,c=2

  • x-value of the vertex:

x=-b/2a

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

x=3

  • y-value of the vertex:

put value of x in the given equation

y=-3(3)^2+18(3)+2

y=-27+54+2

y=29

  • Write down the x and y values as an ordered pair.

x=3 y=29

(3,29)
