Introduction to Limits
Lesson summary
Lesson summary
- The limit of f at a is the value that f(x) approaches as x approaches a. It does not necessarily depend on f(a).
- The limit exists when the right-hand and left-hand limits are equal.
- Limits can be estimated from a table of values or from a graph.
- If a function is continuous at a, then the limit at a equals f(a).
