given dа ta:
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
