Unformatted text preview: lim x a + f x ( ) = L ). That is, a two-sided limit exists the left-hand and right-hand limits exist, and they equal the same real constant. The value of the two-sided limit then equals that constant. If either one-sided limit does not exist (DNE), or if the two one-sided limits exist but are unequal, then the two-sided limit does not exist (DNE). Example 7 (Revisiting Examples 5 and 6) lim x 3 x + 3 ( ) = 6 , and lim x 3 + x + 3 ( ) = 6 , so lim x 3 x + 3 ( ) = 6 ....
