True or False? b). If f(4) = 9, then it must be true that lim f(x) = 9 X - 4 If the statement is TRUE, explain why. If the statement is FALSE, sketch the graph of a counterexample. True False 7. True or False? b). If lim f(x) = DNE, then f(5) = DNE. x-5 If the statement is TRUE, explain why. If the statement is FALSE, sketch the graph of a counterexample. True False
