Code in matlab

Problem 1: Consider the polynomials: Pz() = $3 + 5s+ 3s + 10 pg(s) = 84 + 783 + 5s+8s + 15 pz(s) = 35 + 1584 + 1083 +682 + 38 + 9 Use MATLAB to evaluate the following (make sure to obtain polynomial expressions): a. pl(3) b. p3(1) c. pl(s) *p2(s) *p3(s) d. pl(s)*p2(s)/p3(s) Problem 2: Given the function y: y = (xV2 +0.02 + ex)8 In x Use Symbolic Math Toolbox functions in MATLAB to determine the values of y for the following values of x: -4, 5 and 11. Problem 3: Determine the roots of the following polynomials using MATLAB: p1(x) = x+ + 8x6 + 5x5 + 4x4 + 3x3 + 2x + x + 1 P3(x) = x5 13x4 + 10x3 + 12x2 + 8x 15
