Solve problem 2 3 and 4 using matlab and include the screenshot of the code please , thank you

command. Ensure that you organize each problem properly and answer the question fully. Also ensure that your answers make sense 1. Use the Matlab function, integral( ) to numerically integrate the function, y= x2-2x-4 from 1 to 5. You will have to create a function and pass afunction handle togtaal . ) . See Attaway 14.5. (Answer =-4/3) 2. Write a function using "for-loops" to integrate the mathematical function in Problem #1 using Rectangular integration. Use "Left-corner" Rectangular Integration. The function should take as inputs, a, b, N and a function handle and output the integrated result. (try N-1000) (Answer 4/3) 3, Using "for-loops", integrate the same function in Problem #1 using Trapezoidal integration. Use the same function structure as in Problem #2. (Answer -4/3) 4. Using "for-loops", integrate the same function in Problem #1 using Simpson's 13 and 38 Rule integration. Use the same function structure as in Problem #2. try N-100) (Answer43) command.
