Q. Is the following function even, odd, or neither?f(x)=4x+2Choose 1 answer:(A) Even(B) Odd(C) Neither
Check Even Function: To determine if the function f(x)=4x+2 is even, odd, or neither, we need to check the symmetry properties of the function. An even function satisfies the condition f(x)=f(−x) for all x in its domain, while an odd function satisfies the condition f(−x)=−f(x) for all x in its domain. Let's first check if f(x) is even.
Calculate f(−x): We calculate f(−x) for the given function f(x)=4x+2. Substituting −x into the function, we get f(−x)=4(−x)+2=−4x+2.
Compare f(−x) with f(x): Now we compare f(−x) with f(x). We have f(x)=4x+2 and f(−x)=−4x+2. Since f(x)=f(−x), the function is not even.
Check Odd Function: Next, we check if f(x) is odd by verifying if f(−x)=−f(x). We already calculated f(−x)=−4x+2. Now we need to calculate −f(x), which is −f(x)=−(4x+2)=−4x−2.
Calculate −f(x): Comparing f(−x) with −f(x), we have f(−x)=−4x+2 and −f(x)=−4x−2. Since f(−x) does not equal −f(x), the function is not odd.
Compare f(−x) with −f(x): Since the function f(x)=4x+2 is neither even nor odd, the correct answer is (C) Neither.
