The domain is the set of all possible x-values which will make the function "work", and will output real y-values
[tex]\begin{gathered} \text{Let} \\ f(x)=5x^6 \\ \end{gathered}[/tex]there is not a value for x, that makes the function does not "work", so x can take any value, in other words all real numbers
so, the answer is all real numbers
