Solution
Correct Answer:
Neither even nor odd
- Even Property Check: Requires f(−x)=f(x).
- f(−x)=∣−x∣−(−x)=∣x∣+x.
- This is not equal to ∣x∣−x for all x=0. Not even.
- Odd Property Check: Requires f(−x)=−f(x).
- −f(x)=−(∣x∣−x)=x−∣x∣.
- This is not equal to ∣x∣+x for all x. Not odd.
- Logical Verification: For x=1,f(1)=0. For x=−1,f(−1)=2. Since f(−1) is neither f(1) nor −f(1), the function is neither even nor odd.
