Answer:
Even
Step-by-step explanation:
Let x be any real number,
We know that the cubes of odd and even numbers are odds and evens respectively....
Hence,
If x was odd then,
[tex]f(Odd)=(Odd)^3+Odd\\f(Odd)=Odd+Odd\\f(Odd)= Even[/tex]
If x was even then,
[tex]f(even)=(even)^3+even\\f(even)=even+even\\f(even)=even[/tex]
