Consider the following functions. What would be the response to the command line t = fun(5, 2) + fun(3, 4)? function [t] = fun(x, y) if x == 0 t = y: else t = fun(x - 1, x + y): end end Consider the following functions. What would be the response to the call foo(5)? Note that there is both a returned value and side effects. function x = foo(n) if mod (n, 2) == 1 disp(n): end if n > = 2 x = n - 2 + 3 * bar(n - 1): else x = 3: end function x = bar(n) if mod(n, 3) = 1 disp(n) end if n > = 2 x = 2 * n + 2 - foo(n - 1) else x = -2: end
