Definition
When we say that x "approaches infinity," it means that x gets larger and larger without bound. As x becomes extremely large, we analyze how the behavior of the function changes.
Divergence occurs when the output of a function becomes infinitely large or does not approach any specific value as the input approaches a certain point.
Horizontal Asymptote: A horizontal asymptote is a horizontal line that a function approaches as x goes towards positive or negative infinity.
