Answer:
3,-3
Step-by-step explanation:
g(3)= (3)³+6(3)²-9(3)-54
 = 27+54-27-54
 =81-81
 = 0
g(-3) = (-3)³+6(-3)²-9(-3)-54
 = -27+54+27-54
 = 27-27
 = 0

Just substitute x = 2 and y = 5 into the equation wherever you see x and y.
2 + (12 - 5x) · 2y
2 + (12 - 5(2)) · 2(5)
2 + (2) · 10
4 · 10
40, is the answer which should be the first box.
