Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Limits
A limit describes the behavior of a function as its input approaches a certain value. It is essential for understanding continuity and the behavior of functions near points where they may not be explicitly defined. In this context, we are interested in the limit of f(x) as x approaches 2, which helps determine the function's value or behavior at that point.

One-Sided Limits
Continuity
A function is continuous at a point if the limit of the function as it approaches that point equals the function's value at that point. For the function f(x) given, checking continuity at x = 2 involves evaluating the limit as x approaches 2 and comparing it to f(2). If they are not equal, the function is discontinuous at that point.

Intro to Continuity
Indeterminate Forms
Indeterminate forms occur in calculus when evaluating limits leads to expressions like 0/0 or ∞/∞, which do not provide clear information about the limit's value. In this case, as x approaches 2, both the numerator and denominator of f(x) approach 0, indicating an indeterminate form. Techniques such as L'Hôpital's Rule or algebraic manipulation may be needed to resolve these forms and find the limit.
