Math Problem Statement
Classify the statement as either true or false.
If
ModifyingBelow lim With x right arrow 9
F(x)
exists, then F
could be continuous
at
xequals
9
.
Solution
The statement is true.
Here's why:
If the limit of as approaches 9 exists, then could potentially be continuous at . However, for to be continuous at , three conditions must be met:
- must be defined.
- must exist.
- .
So, the existence of the limit means that continuity is possible, but other conditions (like being defined and equal to the limit) must also be satisfied for to be continuous at .

Here are 5 related questions:
- What are the formal conditions for a function to be continuous at a point?
- Can a function be continuous if its limit exists but is not equal to its function value at the point?
- How can we determine the existence of a limit at a point?
- What is the difference between one-sided and two-sided limits?
- Can a function have a limit at a point where it is not defined?
Tip: Continuity at a point requires the function's limit at that point to match the function's actual value at that point.
