Let f(x) = r. Construct a table giving the values f(r) for positive a near 0, and use this information to guess the value of lim f(x). Let r +1, for r E (-oo, 0) g(1) = 0. for r = 0 and x = 3 - 1, for r E (0, 3) U (3, 00). Sketch the graph of g, and, for each of the following, use the graph of g to evaluate the given quantity or state that it does not exist. a) g(0) b) lim g(r) c) lim g(x) 040 d) lim g(I) e) g(3) f) lim g(x) -40
