Q. Determine whether the function f(x)=−5x4−1−5x6 is even, odd or neither.oddneithereven
Define function f(x): Define the function f(x). The given function is f(x)=−5x4−1−5x6. 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)=−5(−x)4−1−5(−x)6Simplify the powers of −x.f(−x)=−5x4−1−5x6
Compare f(x) with f(−x): Compare f(x) with f(−x). We have f(x)=−5x4−1−5x6 and f(−x)=−5x4−1−5x6. Since f(−x)=f(x), the function f(x) is an even function.
