Use the graph of the function fx 55 e1x to state the

Question

Use the graph of the function f(x) = 5/(5 + e^(1/x)) to state the value of each limit, if it exists.

a) lim x-> 0- = ? if the left hand limit exists

b) lim x-> 0+ =? if the right hand limit exists

c) lim x-> 0 = DNE the limit DNE because the limits are not equal
