Math Problem Statement
lim x→2+ g(x) = 2 • lim x→2− g(x) = 3 • g(2) is not defined
Solution
The given information specifies:
- , meaning the right-hand limit of as approaches 2 is 2.
- , meaning the left-hand limit of as approaches 2 is 3.
- is not defined.
Conclusion:
Since the left-hand limit () and the right-hand limit () as approaches 2 are not equal, the overall limit of as does not exist. For a function to have a limit at a point, the left-hand and right-hand limits must be equal.
Additionally, is not defined, so there is no value of the function at .
Would you like further details on why the limit does not exist in this case?
Here are some related questions:
- What are one-sided limits, and how are they different from two-sided limits?
- Can a function still be continuous if the left-hand and right-hand limits differ?
- How can we graphically interpret the information about near ?
- What does it mean for a function to be undefined at a point, and how does it affect limits?
- How do we determine the overall limit of a function at a point?
Tip: When checking for limits, always consider both one-sided limits to ensure they match for the overall limit to exist!
