Computer Question 1: Calculating the Value of a Function f(x) = 4e x+2 for -6 <= x < -2 x 2 for -2 <= x < 2 (x+62) 1/3 for 2 <= x <= 6 Write Matlab code that asks the user to enter x, and then displays the value of f(x) for that x. If the user enters a value that is outside of the domain of this function (i.e. x is not between -6 and 6), your code should instead display “Error” x = input( 'Enter x ' ); if (x<-6 | x>6) disp( 'Error' ) elseif (x<-2) f = 4*exp(x+2) elseif (x<2) f = x^2 else f = (x+62)^(1/3) end -6 if they have minor syntax errors that cause their code not to run (they had the computer to check answers) -9 if there are major syntax errors -10 if some of their conditions are wrong, or some of their calculations are wong -12 if there are major flaws with the logic of their program, but seem to understand how if and input work -14 if they have no idea Computer Question 2: Sum of Composites Run the following commands, which create a 100 element matrix B : rand( 'state' , 4 ) ; B = round( 120*rand(10,10) - 10 ); Write Matlab code that calculates the sum of all of the numbers in B

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
