    Domain is the x-values

    Range is the y-values

    To identify the range, plug in the x-values they gave you into the equation to find its y-value

    x = 3

    y = 2x + 4       Plug in 3 for x

    y = 2(3) + 4

    y = 10

    x = 5

    y = 2x + 4    Plug in 5 for x

    y = 2(5) + 4

    y = 10 + 4

    y = 14

    x = 6

    y = 2x + 4       Plug in 6 for x

    y = 2(6) + 4

    y = 16

    x = 8

    y = 2x + 4      Plug in 8 for x

    y = 2(8) + 4

    y = 20

    The range is {10, 14, 16, 20}
