Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Vertical Asymptotes
Vertical asymptotes occur in a function when the output approaches infinity as the input approaches a certain value from either the left or the right. This typically happens at points where the function is undefined, often due to division by zero. Identifying these points is crucial for understanding the behavior of the function near those values.

Limits
Limits are fundamental in calculus, representing the value that a function approaches as the input approaches a certain point. In the context of vertical asymptotes, evaluating the left-hand limit (lim x→a<sup>-</sup> f(x)) and the right-hand limit (lim x→a<sup>+</sup> f(x)) helps determine the behavior of the function near the asymptote, indicating whether it approaches positive or negative infinity.

Function Behavior
Understanding the behavior of a function involves analyzing how it changes as the input varies, particularly near critical points like vertical asymptotes. This includes observing trends such as increasing or decreasing values, and how the function behaves as it approaches the asymptote from either side, which is essential for sketching the graph and predicting the function's overall shape.
