MATLAB Problem

Write a script file to plot the function f (x) = x^3 - 2x^2 - 10 sin^2 (x) - e^0 9x and its derivative f' (x) = 3x^2 - 4x - 20 sin (x) cos (x) - 0.9e^0.9x for - 2 lessthanorequalto x lessthanorequalto 4 in ONE PLOT. Plot f(x) with a solid red line and f' (x) with a dashed blue line; include a legend. The pressure p, volume V, and temperature T of an ideal gas are related by the following equation: p middot V = n R T, where n is the number of moles and R = 8.3145 J/(K mol) is the ideal gas constant. Plot pressure over volume (called an isotherm) for 1 mole of an ideal gas at temperatures of T = 100, 200, 300, and 400K for volumes ranging from 1 to 10 m^3 (four curves/graphs in ONE PLOT using the hold command). Choose different line COLORS/STYLES that make the curves/graphs easy to DISTINGUISH. Label the axes and display a legend
