(a) 0 (b) 1 (c) 2 (d) Infinitely many Which of the following is equal to the limit lim COS(I) (I - 7) , if it exists? T - T (a) -1 (b) 1 (c) 0 (d) Does not exist Suppose that f : R -> R is a function such that lim f(r) does not exist. Which of the following I-+2 statements must be true, for any such function f ? (a) f is not a continuous function at r = 2. (b) At least one of the two limits lim f(x) , lim f(r) must not exist. r-+2 (c) At least one of the two limits lim f(r) , lim f(x) must be infinite. r-+2 (d) f(2) does not exist
