Chapter 5, Problem 5RE

Consider these methods:

 public static double f(double x) { return g(x) + Math.sqrt(h(x)); }

 public static double g(double x) { return 4 * h(x); }

 public static double h(double x) { return x * x + k(x) − 1; }

 public static double k(double x) { return 2 * (x + 1); }

Without actually compiling and running a program, determine the results of the following method calls.

1. a. double x1 = f(2);
2. b. double x2 = g(h(2));
3. c. double x3 = k(g(2) + h(2));
4. d. double x4 = f(0) + f(1) + f(2);
5. e. double x5 = f(-1) + g(−1) + h(−1) + k(−1);
