    Let f (x) = 2x+3 and g (x) = 1/2x - 3/2. Evaluate (fog) (-3)

    First solve for g (x) by replacing x with - 3:

    g (x) = 1/2 (-3) - 3/2

    g (x) = - 3/2 - 3/2

    g (x) = - 3

    Now solve for f (x) by replacing x with - 3:

    f (x) = 2 (-3) + 3

    f (x) = - 6 + 3

    f (x) = - 3

    The answer is - 3
