4. For each condition below, explain what is happening with each limit. Then sketch the graph of an example of a function f that satisfies all of the given conditions. a) lim f (x) = -0o x-+2 b) lim f (x) = 00 X-00 c) lim f(x) = 0 x - -00 d) lim f (x) = 0o *+0+ e) lim f (x) = -co x+0 f) Sketch a possible graph
