Using Matlab only please answer #3.

#1 for reference

2. In 2 separate script files named Initials_HW_05_pb_02a.m and Initials_HW_05_pb_02b.m prompt the user to enter a value for xbetween -5 and 10 and use it to calculate the value of the piecewise function y given in problem 1 and display both x & y using fprintf. a. Use multiple if statements withoutelse or nested if statements. Use the logical AND (&) but do NOT use elseif Draw flow chart. b. Use ONLY ONEif statement with multiple elseif clauses. Draw flow chart. 3. Use one of the solutions of the previous problem (either a or b) to create a function file named Initials y that accepts a single (or array of values in one of the 4 ranges] for x and returns the corresponding value(s) of the piecewise function y given in problem 1
