What to Focus On
- Continuity at c means lim x→c f(x) = f(c).
- A function is continuous if it is continuous at every point of its domain.
- At endpoints of [a, b], one-sided limits are used.
- Discontinuity can come from jump, hole, or mismatch of values and limits.
- +∞ and −∞ are not real numbers.
- A function defined everywhere is not automatically continuous.
- Derivative at c is defined by a limit of the difference quotient.
- Differentiability implies continuity.
- Continuity does not imply differentiability.
Common Mistakes to Avoid
If a function is defined at a point, it is continuous at that point.
A continuous function is always differentiable.
To prove continuity, it is enough to substitute x = c into the formula.
Memory Tips
Continuity at a point
