3943. Precise definitions for left- and right-sided limits Use the following definitions. Assume f exists for all x near a with x 7 a. We say the limit of f 1x2 as x approaches a from the right of a is L and write lim xSa+ f 1x2 = L, if for any e 7 0 there exists d 7 0 such that f 1x2 - L 6 e whenever 0 6 x - a 6 d. Assume f exists for all x near a with x 6 a. We say the limit of f 1x2 as x approaches a from the left of a is L and write lim xSaf 1x2 = L, if for any e 7 0 there exists d 7 0 such that f 1x2 - L 6 e whenever 0 6 a - x 6 d. Comparing definitions Why is the last inequality in the definition of lim xSa f 1x2 = L, namely, 0 6 _ x - a _ 6 d, replaced with 0 6 a - x 6 d in the definition of lim xSaf 1x2 = L?
