FAQs

Question: What is the definition of continuity in mathematics?
Answer: Continuity refers to a function being unbroken or uninterrupted over an interval, meaning small changes in input result in small changes in output.

Question: How can I determine if a function is continuous at a point?
Answer: A function is continuous at a point if the limit exists at that point, the function is defined at that point, and the limit equals the function's value.
