(e) In a certain city the amount of violent crime was decreasing but slower than it was in previous years. If v(t) is the amount of violent crime at time t, what are the signs of r(t), t(t) and u"(t)? Explain your answer. (f) Prove that f(z) = 1.1z+ cos(z) has no more than one root. (Note: It is not enough to have Desmos draw the curve for you. You should appeal to Theorems from class.)
