Math Problem Statement
WHY WE DIDNOT STUDY THE CONTINUOS AT X=2
Solution
We didn't study the continuity at because is the right endpoint of the function's domain. The concept of continuity typically concerns the behavior of the function as approaches a point from both sides.
Key Points:
-
Continuity Definition: For a function to be continuous at a point , the following conditions must be met:
- is defined.
- The limit exists.
- The limit equals .
-
At : The function is defined only up to . There's no need to check the continuity at from the right because the function doesn't extend beyond . We only need to check the left-hand limit:
- As approaches 2 from the left, the function is , so .
- Since this is the endpoint, the function is continuous at if it's defined at this point, which it is because is a valid value.
Thus, there is no requirement to study the continuity at further.

Here are some related questions:
- How would the analysis change if the domain extended beyond ?
- What does it mean for a function to be continuous at a boundary point?
- What if the function were undefined at ?
- How does the continuity at affect the overall behavior of the function?
- Can a function be continuous at only one side of a boundary point?
- How would we test for continuity if the function included ?
- What are the implications of piecewise-defined functions at boundary points?
- How does the concept of left-hand and right-hand limits help in analyzing functions?
Tip: When dealing with endpoints of a domain, consider only the one-sided limit that applies since the function isn't defined beyond the endpoint.
