10.2: Infinite Limits. Infinite Limits. When the limit of f(x) does not exist and f(x) goes to positive infinity or negative infinity, then we can call that an infinite limit. Discuss the behavior of as x 1.

Infinite Limits • When the limit of f(x) does not exist and f(x) goes to positive infinity or negative infinity, then we can call that an infinite limit.
Discuss the behavior of as x 1 • As x goes closer to 1 from the left, f(x) is smaller and smaller • As x goes closer to 1 from the right, f(x) is bigger and bigger
Discuss the behavior of as x 2 • As x goes closer to 2 from the left, f(x) is bigger and bigger • As x goes closer to 2 from the right, f(x) is bigger and bigger

Horizontal asymptote is y = 0 Horizontal asymptote is y = -3/4
There is no horizontal asymptote Horizontal asymptote is y = -1
