Problem 2 - Section 2.2 2 - 3 a) Let f(x) = Find each limit and use -co and oo when appropriate. Show all work. 202 - 4 i) lim f(x) x-2 ii ) lim f(x) x- 2+ iii) lim f(x) x->- 2+ b) A drug is administered to a patient through an injection. The drug concentration (in mil- ligrams/mililiter) in the bloodstream t hours after the injection is given by a model. Consider the two models below: 3t(t + 5) B(t) = 3+2 ( t + 5 ) +3 + 100 C(t) = +3 + 100 i Find an interpret lim B(t). Use complete sentences. t -+ 0o ii Find an interpret lim C(t). Use complete sentences. t-+0o
