Q. Is the following function even, odd, or neither?f(x)=2∣x∣−5Choose 1 answer:(A) Even(B) Odd(C) Neither
Determine Even, Odd, Neither: To determine if the function f(x) is even, odd, or neither, we need to compare f(x) with f(−x). If f(x)=f(−x) for all x, then the function is even. If f(x)=−f(−x) for all x, then the function is odd. If neither condition is met, the function is neither even nor odd.
Find f(−x): Let's find f(−x) by substituting −x for x in the function f(x)=2∣x∣−5. f(−x)=2∣−x∣−5 Since the absolute value of −x is the same as the absolute value of x (∣x∣=∣−x∣), we can simplify this to: f(−x)=2∣x∣−5
Compare f(x) and f(−x): Now we compare f(x) and f(−x): f(x)=2∣x∣−5 f(−x)=2∣−x∣−5 We can see that f(x) and f(−x) are the same for all x. Therefore, the function f(x) is even.
