Use MATLAB to solve following problems. You will be submitting published script. Be sure to comment your code. 10 points will be allocated for formatting. Be sure to do all problems in a single script except for plotting questions. Separate problems using "section" function in script. Be sure to include heading. Be sure to use MATLAB's "publish" function and print the output. Given the equation: f(x)= 3x^2 + 2x - 1. Symbolically solve the following: a) integrate f once with respect to x b) calculate d^2 f/dx^2 c) find x such that f(x) = 0
