2: Limit - Types of Limits

2.1: One-Sided Limit Types
A one sided limit is exactly what you might expect; the limit of a function as it approaches a specific x value from either the right side or the left side. One sided limits help to deal with the issue of a jump discontinuity and the two sides not matching.
2.2: Infinite Limit Type
2.3: Limits of Polynomial and Rational Functions
Finding the limit of a polynomial function is relatively easy. Why? Finding the limit of a rational function can also be relatively easy, except under a few particular conditions. When is finding the limit of a rational function difficult?
