Answer:
The answer is below
Step-by-step explanation:
a) g(10) = -3(10) + 1 = -30 + 1 = -29
b) f(3) = (3)² + 7 = 16
c) h(-2) = 12 / (-2) = -6
d) j(7) = 2(7) + 9 = 14 + 9 = 23
e) h(a) = 12 / (a) = 12 / a
f) g(b + c) = -3(b + c) + 1 = 1 - 3b - 3c
h) g(x) = 16
-3x + 1 = 16
3x = 1 - 16
3x = -15
x = -5
i) h(x) = -2
12 / x = -2
x = 12 / -2 = -6
j) f(x) = 23
23 = x² + 7
x² = 16
x = √16
x = 4
