C-5 Identify the value(s) of a such that x = a is a vertical asymptote of f () = 12-9x+18Consider the graph of the function f below. The dashed line represents a vertical asymptote. The circles are points with integer coordinates. 15 10 y 5 -10 -8 -6 -2 0 2 6 8 ) Give the left and right limits of this functions at the various points specified. Write "inf" for 00 and "-inf for -DO. lim f = I-+-4 lim I+47 lim f = I-+3 lim f = At which of the following values of r does the limit of f exist? The choices are -8; -4;0, 3; 5.identify the following limits: a) lim I-+-00 bj lim et I-+00 c) lim In(
