For the function g whose graph is shown, find a number a that satisfies the given description. (a) lim g(a) does not exist but g(a) is defined. {{4}} (b) lim g(x) exists but g(a) is not defined. {{5}} (c) lim g(x) and lim g(a) both exist but lim g(x) does not exist. {{2|4}} (d) lim g(x) = g(a) but lim g(x) # g(a).
