Answer:
The correct option is 4.
Step-by-step explanation:
Domain is the set of all possible inputs for which the given function is defined.
The given function is
\(y=x^2-6x+1\)
It is a second degree polynomial. These type of polynomial are defined for all real values of x. So, the domain of the given function is all real numbers.
\(Domian=\{x:x\in R\}\)
\(Domian=R\)
Therefore the correct option is 4.
