Q. Is the following function even, odd, or neither?f(x)=x4+xChoose 1 answer:(A) Even(B) Odd(C) Neither
Symmetry properties of a function: 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, while an odd function satisfies f(−x)=−f(x) for all x in its domain.
Checking if f(x) is even: Let's first check if f(x) is even. We substitute −x for x in the function and see if we get the original function back.f(−x)=(−x)4+(−x)=x4−x
Checking if f(x) is odd: We can see that f(−x)=f(x), because f(x)=x4+x and f(−x)=x4−x. Therefore, the function f(x) is not even.
Conclusion: Next, let's check if f(x) is odd. We substitute −x for x in the function and see if we get the negative of the original function.f(−x)=(−x)4−x=x4−x
Conclusion: Next, let's check if f(x) is odd. We substitute −x for x in the function and see if we get the negative of the original function.f(−x)=(−x)4−x=x4−x We can see that f(−x) does not equal −f(x), because −f(x) would be −x4−x, which is not equal to x4−x. Therefore, the function f(x) is not odd.
Conclusion: Next, let's check if f(x) is odd. We substitute −x for x in the function and see if we get the negative of the original function.f(−x)=(−x)4−x=x4−xWe can see that f(−x) does not equal −f(x), because −f(x) would be −x4−x, which is not equal to x4−x. Therefore, the function f(x) is not odd.Since f(x) is neither even nor odd, the correct answer is that the function is neither even nor odd.
