Question
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. a) double x1 = f(2);
b) double x2 = g(h(2));
c) double x3 = k(g(2) + h(2));
d) double x4 = f(0) + f(1) + f(2);
e) double x5 = f(-1) +
g(-1) + h(-1) + k(-1);
Explanation / Answer
a) double x1 = f(2);
39.0
b) double x2 = g(h(2));
400.0
c) double x3 = k(g(2) + h(2));
92.0
d) double x4 = f(0) + f(1) + f(2);
62.0
e) double x5 = f(-1) + g(-1) + h(-1) + k(-1);
