Answer: Range = {2, 4, 8}
Step-by-step explanation:
The given function is:
f(x) = x + 4
Domain = { -2, 0, 4}
To calculate the range, every element in the domain will be substituted into the given function
when x = -2
f(-2) = -2 + 4 = 2
When x = 0
f (0) = 0 + 4 = 4
when x = 4
f(4) = 4 + 4 = 8
Therefore the range will be:
Range = {2, 4, 8}
