Full solution

Q. Is the function r(x)=3x6+x2r(x) = 3x^6 + x^2 even, odd, or neither?\newlineChoices:\newline(A)even\newline(B)odd\newline(C)neither
  1. Define function r(x)r(x): r(x)=3x6+x2r(x) = 3x^6 + x^2\newlineSelect the function for r(x)r(-x).\newlineSubstitute x-x for xx in r(x)=3x6+x2r(x) = 3x^6 + x^2.\newliner(x)=3(x)6+(x)2r(-x) = 3(-x)^6 + (-x)^2
  2. Substitute x-x in r(x)r(x): r(x)=3(x)6+(x)2r(-x) = 3(-x)^6 + (-x)^2\newlineSimplify the right side of the function.\newliner(x)=3x6+x2r(-x) = 3x^6 + x^2
  3. Simplify r(x)r(-x): We have:\newliner(x)=3x6+x2r(x) = 3x^6 + x^2\newliner(x)=3x6+x2r(-x) = 3x^6 + x^2\newlineIs the function r(x)r(x) even, odd, or neither?\newlineSince r(x)=r(x)r(-x) = r(x), r(x)r(x) is an even function.
