Find f(−x): Find expression for f(−x)f(−x)=∣−x∣1Since ∣−x∣=∣x∣, we have f(−x)=∣x∣1
Check equality of f(−x): Check if f(−x) is equal to f(x) or −f(x) Since f(−x)=∣x∣1 and f(x)=∣x∣1, f(−x) is equal to f(x)
Conclusion: ConclusionRon concluded that since f(−x) is equivalent to f(x), f is odd. However, this is incorrect because if f(−x)=f(x), the function is even, not odd.
