Please help me with my matlab problems thanks

giaueu. Upel a new igife by uing the figure 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, yx-2x-4 from 1 to 5. You will have to create a function and pass a function handle to quad (-) . See Attaway 14.5. (Answer =-4/3) 2. Write 3 functions using '"for-loops" to integrate the mathematical function in Problem #1 using Rectangular integration. Use "Left-comer", "Midpoint" and "Right-corner" Rectangular Integration. The function should take as inputs, a, b N and a function handle and output the integrated result. (try N-1000 Write a function using "for-loops" to integrate the same function in Problem #1 using Trapezoidal integration. Use the same function structure as in Problem #2. try N-1000) 3. write 2 functions using "Yor-loops" to integrate the same function in Problem #1 using Simpson's 1/3 and 3/8 Rule integration. Use the same function structure as in Problem #2. (try N 100) 4, Use the 3 functions from Problem #1 to integrate the Gaussian normal distribution curve from [-o, ], [-2o; 2], and [-3, 3], using Rectangular integration. Perform all 3 types of Rectangular integration: 1) Left-corner; 2) Midpoint and 3) Right-corner. Use the same function structure as in Problem #2. Let be 0 and let be l. (try N-1000) (Answer =-68.2%,-95.4%,-99.7%) 5. 2(
