2. Find each limit using algebraic techniques: (a) lim Vx - +9-5 x+2 x --4 x+4 (b) lim - x2x3+8 3. Show that lim Vx . esin (x/x) = 0.(C) 0) 93mm] (ii) Lgrxhix (D) Explain any results that found important or interesting from parts (A), (B), and (C). ***More problems on the next page*** Section 2.3 Activity; 1. Given below are four functions, f (x) , g(x) , h(x), and j(x) . Use the functions and according limit laws to nd each indicated limit. If a limit does not exist, then explain why. y=f(x) y=g(x) x2 -4 1 if x
