2. Suppose f(1:),g(a:), and MI) are differentiable functions. A. List all the different ways it is possible to choose two of the functions f(1:),g(a:), and h(?) and compose them with one another. B. Now suppose x) is decreasing, 9(x) is constant, and MI) is increasing. Explain whether each of the composite functions that you listed in part A is decreasing, constant, or increasing, or whether it is impossible to tell. Make sure that any arguments you give are general. Showing that something is true for a particular example does not prove that it's always true
