This topic focus on the intuitive approach. The intuitive approach help to grasp the fundamental concept of learning the behavior of a function as x approach to a particular value we called as 'a'. Using this approach, students are required to graph the function and observed the values as it get closer to a from the left and the right. There 4 examples given in this subtopic to assist students in understanding the concept of intuitive approach.

The topic on one-sided limit focuses on the limit approaching from one side (direction), either from the left or right. The notation is the superscript '+' or '-' indicates the from the right or left respectively. At the end of this topic, students will understand that the limit exist only if the one-sided limits approaching to the same value.

This topic explains certain functions, particularly for rational functions where they have points at which they are not defined but approach closely to a vertical line called as vertical asymptotes. It is said that the function is increases without bound or decreases without bound.

This topic focuses of algebraic approach of finding limits. The common techniques used are direct substitution, factoring and simplification and conjugate pairs.

This topic explains the limit of a function as x approaches to positive or negative infinity. Contradicts to infinite limits, this topic concerned with the behavior of the function as x increases or decreases without bound.
