R$5\mathrm{.}5$ Consider these methods:

public static double double $x\{$return $g(x)+$Math.$\sqrt[\phantom{2}]{h(x)}$; $\}$

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 $1=f(2)$;

b$.$ double $2=g(h(2))$;

c$.$ double $3=k(g(2)+h(2)){}^{}$

d$.$ double $x4=f(0)+f(1)+f(2)$;

e$.$ double $5=f(-1)+g(-1)+h(-1)+k(-1)$;
