The aim of this exercise is to write a MATLAB code that test if the input en +ln(n) n is a multiple of 3, then the output value is -, otherwise it returns 3 0. The code is structured as below function [value] = test (n) if ......... value else value end end 0; 1. Line 2 should be completed as a. if n = 3*k; b. if mod(n,3) = 0; c. if mod(n,3) == 0; d. None of the above 2. Line 3 should be completed as a. value = (e^n+ln(n))/3^n; b. value = (exp(n) + In(n))/3^n; c. value = (exp(n) + log(n))/3^n; d. None of the above 3. Test your script with n = 9, then value = a. O b. 0.4118 c. 0.5689 d. None of the above
