    f(x) = 3x - 1; g(x) = 15 - 3*f(x) The functions f and g are defined above. What is the value of g(2)?

    g(2) = 15 - 3 * f(2)

    f(2) = 3(2) - 1
    f(2) = 6 - 1
    f(2) = 5

    Therefore, with f(2) = 5, g(2) is:
    g(2) = 15 - 3 * f(2)
    g(2) = 15 - 3 * 5
    g(2) = 15 - 15
    g(2) = 0
