The student response accurately includes both of the criteria:
1. What is the limit of f(x) as x approaches infinity?
a) 2
b) 0
c) 1
d) Does not exist
2. What is the limit of f(x) as x approaches negative infinity?
a) 2
b) 0
c) 1
d) Does not exist
Solution:
The limit of f(x) as x approaches infinity is (2e^x)/(2-e^x).
