    The range: {0, 10, 42}

    Step-by-step explanation:

    Put the values of x from the domain to the equation of the function

    f (x) = 2x² - 8

    for x = - 2

    f (-2) = 2 (-2) ² - 8 = 2 (4) - 8 = 8 - 8 = 0

    for x = 3

    f (3) = 2 (3) ² - 8 = 2 (9) - 8 = 18 - 8 = 10

    for x = 5

    f (5) = 2 (5) ² - 8 = 2 (25) - 8 = 50 - 8 = 42
