Math Problem Statement
Evaluate: , x < 0
Solution
The expression given is:
This limit is evaluated as approaches 0 from the left side, which is indicated by . Let's analyze the behavior of the expression as approaches 0 from the left (i.e., ).
Step 1: Analyze as
When is a small negative number, becomes a large negative number. Therefore, approaches 0 because the exponential function approaches 0 as becomes very negative.
Step 2: Substitute the behavior into the limit
As , tends to 0. Thus, the expression simplifies as:
Conclusion
Therefore, the limit is:
Would you like to explore any related concepts or have any other questions? Here are a few related topics you might find interesting:
- What happens to the limit if approaches 0 from the right (i.e., )?
- How does the behavior of the exponential function change as its exponent becomes very large or very small?
- Can this type of limit be evaluated using L'Hôpital's Rule? Why or why not?
- What are the key differences between limits approaching from the left and from the right?
- How do exponential functions behave compared to polynomial or logarithmic functions as their input approaches infinity or negative infinity?
Tip: When evaluating limits, especially as approaches a particular value, always consider the direction from which is approaching, as this can significantly impact the result.
