The initial substitution of x = a yields the form olo Simplify the function algebraically, or use a table or graph to determine the limit. If necessary, state that the limit does not exist x2 + 3x - 418 lim X->19 x - 361 Select the correct choice below and, if necessary, fill in the answer box to complete your choice x2 + 3x - 418 O A. lim (Type an integer or a simplified fraction.) X->19 x - 361 O B. The limit does not exist
