Q. Is the following function even, odd, or neither?f(x)=x+1x3Choose 1 answer:(A) Even(B) Odd(C) Neither
Check Symmetry Properties: To determine if the function f(x) is even, odd, or neither, we need to check the symmetry properties of the function. An even function satisfies f(x)=f(−x) for all x in its domain, and an odd function satisfies f(−x)=−f(x) for all x in its domain.
Check if f(x) is Even: First, we will check if f(x) is even. We calculate f(−x) and see if it is equal to f(x).f(−x)=((−x)3)/((−x)+1)=(−x3)/(−x+1)=−x3/(1−x)
Compare f(−x) with f(x): Now we compare f(−x) with f(x).f(x)=x+1x3f(−x)=1−x−x3We can see that f(−x) is not equal to f(x), because f(x) has x+1 in the denominator, while f(−x) has f(x)1 (which is f(x)2(x+1)). Therefore, f(x) is not even.
Check if f(x) is Odd: Next, we will check if f(x) is odd. We calculate f(−x) and see if it is equal to −f(x). We already have f(−x)=−1−xx3 Now we calculate −f(x)=−(x+1x3)=−x+1x3
Compare f(−x) with −f(x): We compare f(−x) with −f(x). f(−x)=1−x−x3 −f(x)=x+1−x3 We can see that f(−x) is not equal to −f(x), because the denominators are different: (1−x) is not the same as (x+1). Therefore, −f(x)0 is not odd.
Conclusion: Since f(x) is neither even nor odd, the correct answer is (C) Neither.
