Answer:
Step-by-step explanation:
11.
f(-8) = (-3/2)(-8) +11 = (24/2) +11 = 12+11 = 23
12.
g(-2) substitute x by -2 in the g( x) equation
9(-2) = (-2)²-7(-2) = 4 +14 = 18
13.
h(2/3) = | 15 -9(2/3)| = | 15 -(18/3)| = | 15 -6 | = |9| = 9
12.
the zero is at x= -2 because is the intersection of the graph with the x-axis
13.
the zero are at x=1, x= -2, x= -4 because is the intersection of the graph with the x-axis
