hello i need help on these calc problem

Find e}, He + h}, and the diFferenoe quotient for the Function given below, where h =-= I]. It) \fEXAMPLE 8 Prove that the limit does not exist. lim Jx - 21 x -2 x - 2 SOLUTION lim x - 21 = lim X - 2 = X - 2+ X - 2 X X - 2+ X - 2 lim x - 2 = lim 2 -X = x - 2 X - 2 x -2- X - 2 X Since the right- and left-hand limits are different, it follows from this theorem that the limit does not exist. The graph of the function (x) = (x - 21/(x - 2) to the left supports the one-sided limits that we found
