Answer:
Range us {0, 6, 12, 18, 24}.
Explanation:
The range of a function is the output values after inputting the domain.
To find these, substitute the values of the domain.
f(x)=12-3x
f(-4) = 12 - 3(-4) = 12 + 12 = 24
f(-2) = 12 -3(-2) = 12 + 6 = 18
f(0) = 12 -3(0) = 12-0 = 12
f(2) = 12 -3(2) = 12-6 = 6
f(4) = 12 -3(4) = 12-12 = 0
The range is {0, 6, 12, 18, 24}.
