    To solve which ordered pair lie on the graph of the given function f (x) = 128 (0.5^2)

    You mus substitute each ordered pair then check if it satisfy the given function

    (0,1)

    1 = 128 (0.5^0)

    1 = 128 so wrong

    (1, 64)

    64 = 128 (0.5^1)

    64 = 64 correct

    (3, 16)

    16 = 128 (0.5^3)

    16 = 16 correct

    0.5 = 128 (0.5^8)

    0.5 = 0.5 correct
