Consider the function given below. 0. XS2 Q f(x)= 1 COS X-2 X2 TH Complete parts (a) through (c). (a) Does lim f(x) exist? If so, what is it? If not, why not? (a) Does lim f(x) exist? If so, what is it? If not, why not? O A. Yes, lim (x) (Simplify your answer.) OB. No, because there is no real number to which the function's values stay increasingly close as x approaches 2 from the right side
