Write a Matlab script that plots the following functions over 0 ≤ x ≤ 5π: f1(x) = sin2 x − cos x, f2(x) = −0.1 x 3 + 2 x 2 + 10, f3(x) = e −x/π , f4(x) = sin(x) ln(x + 1). The plots should be in four separate frames, but all four frames should be in one figure window. To do this you can use the subplot command to create 2 × 2 subfigures.
