See a solution process below:

To find the range for this problem we need to substitute each value of the domain into the function and determine the results.

x = -2

#f(-2) = -(-2) + 5 = 2 + 5 = 7#

x = 0

#f(0) = -(0) + 5 = 5#

x = 3

#f(3) = -3 + 5 = 2#

x = 8

#f(8) = -8 + 5 = -3#

The Domain Is: #{7, 5, 2, -3}#
