Question

Evaluate the given limits using the graph of the function f(x) = 2 / (e^x + 1) shown above. Enter INF for ?, -INF for -?, or DNE if the limit does not exist, but is neither ? nor -?. If you are having a hard time seeing the picture clearly, click on the picture. It will expand to a larger picture on its own page so that you can inspect it more clearly. a) lim_{x ? -?} f(x) = b) lim_{x ? ?} f(x) = c) lim_{x ? 0^-} f(x) = d) lim_{x ? 0^+} f(x) = e) lim_{x ? 0} f(x) =

Evaluate the given limits using the graph of the function f(x) = 2/(e^x + 1) shown above. Enter INF for ∞, -INF for -∞, or DNE if the limit does not exist, but is neither ∞ nor -∞. If you are having a hard time seeing the picture clearly, click on the picture. It will expand to a larger picture on its own page so that you can inspect it more clearly. a) lim_{x→-∞} f(x) = b) lim_{x→∞} f(x) = c) lim_{x→0^-} f(x) = d) lim_{x→0^+} f(x) = e) lim_{x→0} f(x) =
