Answer:
The range = {-4, -1, 2, 8, 17}
Step-by-step explanation:
Put all values of x from the domain {-2, -1, 0, 2, 5} to f(x) = 3x + 2:
x = -2
f(-2) = 3(-2) + 2 = -6 + 2 = -4
x = -1
f(-1) = 3(-1) + 2 = -3 + 2 = -1
x = 0
f(0) = 3(0) + 2 = 0 + 2 = 2
x = 2
f(2) = 3(2) + 2 = 6 + 2 = 8
x = 5
f(5) = 3(5) + 2 = 15 + 2 = 17
