1. Prepare a Matlab script that does the following: Defines an anonymous function for f = r2- . Generates and saves for example as c) a sampling array on the interval [-715, 10) with a sampling distance of 100. Evaluates the function on this array to generate the evaluations (for example as y). Plots the graph of this function using these arrays. Also save the resulting graph as graphl.png and attach to your submission. So, your solution to this question should contain script1.m and graph1.png or jpg or pdf
