Q. Determine whether the function f(x)=−7x3−x4 is even, odd or neither.evenoddneither
Define f(x): Define the function f(x). The given function is f(x)=−7x3−x4. To determine if the function is even, odd, or neither, we need to compare f(x) with f(−x).
Calculate f(−x): Calculate f(−x).Substitute −x for x in f(x) to get f(−x).f(−x)=−7(−x)3−(−x)4f(−x)=−7(−x3)−x4
Simplify f(−x): Simplify f(−x). Simplify the expression for f(−x). f(−x)=−7(−x3)−x4f(−x)=7x3−x4
Compare f(x) with f(−x): Compare f(x) with f(−x). We have f(x)=−7x3−x4 and f(−x)=7x3−x4. Since f(−x) is not equal to f(x) and f(−x) is not equal to −f(x), the function is neither even nor odd.
