Q. Determine whether the function f(x)=8x4+x2+x6 is even, odd or neither.oddevenneither
Select function for f(−x):f(x)=8x4+x2+x6Select the function for f(−x).Substitute −x for x in f(x)=8x4+x2+x6.f(−x)=8(−x)4+(−x)2+(−x)6
Substitute −x in f(x):f(−x)=8(−x)4+(−x)2+(−x)6Simplify the right side of the function.f(−x)=8x4+x2+x6
Simplify right side: We have: f(x)=8x4+x2+x6f(−x)=8x4+x2+x6Is the function f(x) even, odd, or neither?We have f(x)=8x4+x2+x6 and f(−x)=8x4+x2+x6.Since f(−x)=f(x), f(x) is an even function.
