Q. Is the following function even, odd, or neither?\newlinef(x)=x3x+1 f(x)=\frac{x^{3}}{x+1} \newlineChoose 11 answer:\newline(A) Even\newline(B) Odd\newline(C) Neither
  1. Check Symmetry Properties: To determine if the function f(x)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)f(x) = f(-x) for all xx in its domain, and an odd function satisfies f(x)=f(x)f(-x) = -f(x) for all xx in its domain.
  2. Check if f(x)f(x) is Even: First, we will check if f(x)f(x) is even. We calculate f(x)f(-x) and see if it is equal to f(x)f(x).\newlinef(x)=((x)3)/((x)+1)=(x3)/(x+1)=x3/(1x)f(-x) = ((-x)^3)/((-x)+1) = (-x^3)/(-x+1) = -x^3/(1-x)
  3. Compare f(x)f(-x) with f(x)f(x): Now we compare f(x)f(-x) with f(x)f(x).f(x)=x3x+1f(x) = \frac{x^3}{x+1}f(x)=x31xf(-x) = \frac{-x^3}{1-x}We can see that f(x)f(-x) is not equal to f(x)f(x), because f(x)f(x) has x+1x+1 in the denominator, while f(x)f(-x) has f(x)f(x)11 (which is f(x)f(x)22(x+11)). Therefore, f(x)f(x) is not even.
  4. Check if f(x)f(x) is Odd: Next, we will check if f(x)f(x) is odd. We calculate f(x)f(-x) and see if it is equal to f(x)-f(x). We already have f(x)=x31xf(-x) = -\frac{x^3}{1-x} Now we calculate f(x)=(x3x+1)=x3x+1-f(x) = -\left(\frac{x^3}{x+1}\right) = -\frac{x^3}{x+1}
  5. Compare f(x)f(-x) with f(x)-f(x): We compare f(x)f(-x) with f(x)-f(x).
    f(x)=x31xf(-x) = \frac{-x^3}{1-x}
    f(x)=x3x+1-f(x) = \frac{-x^3}{x+1}
    We can see that f(x)f(-x) is not equal to f(x)-f(x), because the denominators are different: (1x)(1-x) is not the same as (x+1)(x+1). Therefore, f(x)-f(x)00 is not odd.
  6. Conclusion: Since f(x)f(x) is neither even nor odd, the correct answer is (C)(C) Neither.
