    so, you have to compare these values: minimum value of f(x), minimum value of g(x), and minimum value of h(x)

    hint: the minimum value of g(x) is -11

    so the max for g(x) is -2

    for f(x) it's 3 and g(x) 3?

    the minimum value of f(x) is -1, and the minimum value of h(x) is also -1

    Oh ok, the question is asking for max value though

    In that case, we have: max value of f(x)=3 max value of g(x) = -2 max value of h(x)= 3

    so the answer would be d, f(x) and h(x)
