Answer:
a = -18
b = 7
c = 27
Explanation:
given f(x) = 5x - 8
Simply go down the table and substitute each value of x into the function and report the final answer:
when x = -4,
f(-4) = 5(-4) - 8 = -28
when x = -2
f(-2) = 5(-2) - 8 = -18 (Answer a)
when x = 3
f(3) = 5(3) - 8 = 7 (Answer b)
when x = 7
f(7) = 5(7) - 8 = 27 (Answer c)
