Problem 16 (#2.3.34).Let f(x) = ax +b, and g(x) = cx +d. Find a condition
on the constants a, b, c, d such that f◦g=g◦f.
Proof. By definition, f◦g(x) = a(cx +d) + b=acx +ad +b, and g◦f(x) =
c(ax +b) + d=acx +bc +d. Setting the two equal, we see
acx +ad +b=acx +bc +d
ad +b=bc +d
(a−1)d=(c−1)b
That last step was merely added for aesthetic reasons.

For each dif erential equation in Problems 1–21, find the general solutionby finding the homogeneous solution and a particular solution.
Please DO NOT YOU THE PI method where 1/f(r) * x. Dont do that.
Instead do this, assume for yp = to something, do the 1 and 2 derivative of it and then plug it in the equation to find the answer.

- Problem 4.2 (Textbook: Figure 2.5 on P84): Hypothetically, a patient is diagnosed to have P, coronavirus at time t = 0 and these viruses grow subsequently (nobody really knows the truth but we assume) according to = -aP(M – P) where P(t) is the number of the cells at time t while a and M are two given positive constants.
