Evaluate limx→2 ( x / |x-2| ).
-2 |
-∞ |
2 |
+∞ |
The limit does not exist. |
Yanıt Açıklaması:
Since the denominator of the expression at x = 2 is 0, we must look at the one-sided limits in order to find the limit at x = 2 if it exists. Then we have,
limx→2+ ( x / |x-2| ) = limx→2+ ( 2 / 0+ ) = +∞
limx→2- ( x / |x-2| ) = limx→2- ( 2 / 0+ ) = +∞
Hence, since the one-sided limits show the same behavior at x = 2, the limit exist at x =2, and it is +∞.
