What is \lim_{x\rightarrow-1}f(x) equal to?
For the following three (03) items: Consider the function f(x)=x|x|.
- A. -1 ✓
- B. 0
- C. 1
- D. Limit does not exist
Correct Answer: A. -1
Explanation
The function f(x) = x|x| is continuous everywhere. To find the limit as x \to -1, simply substitute x = -1 into the function: f(-1) = -1|-1| = -1(1) = -1.
