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: ${7, 5, 2, -3}$
