Problem #1 (20 points): Write a script in Matlab and save it as.m file with name HW16_1. The script will execute the following tasks: a) Let the mathematical function f(x) be defined as: f(x) exp(-0.5x)cos(10x) Use fzero() to find the zero of f(x) @ xO-0.1 b) Find the roots of the following polynomial using roots command g(x) = x4-2x3 +x-5 Submit the script as a .m file. (Note: Script is a list of commands which is different from functions)
