See a solution process below:

Explanation:

The Domain normally represents the x values in an equation. Therefore, to find the range (which normally represents the y values in an equation) we need substitute each value in the Domain and solve for y. The set of answers obtained will for the Range:

For x = 0: y = (3 * 0) - 5 = 0 - 5 = -5

For x = 1: y = (3 * 1) - 5 = 3 - 5 = -2

For x = 1: y = (3 * 2) - 5 = 6 - 5 = 1

For x = 1: y = (3 * 3) - 5 = 9 - 5 = 4

Range = {-5, -2, 1, 4}
