Find each indicated quantity if it exists. Let f(x) = 2+x, for x ≤ 0 2-x, for x>0 Complete parts (A) through (D). (A) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. lim f(x)= (Type an integer.) OB. The limit does not exist. (B) Select the correct choice below and, if necessary, fill in the answer box to complete your choice O A. lim f(x) = x-0 (Type an integer.) B. The limit does not exist. (C) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. lim f(x) = X-0 (Type an integer.) B. The limit does not exist. (D) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. f(0)= (Type an integer.) OB. The function is not defined at x=0.
