Answer:

All real numbers

Explanation:

we have the function


f(x)=x^2-6x+1

This is a vertical parabola open upward

The vertex represent a minimum

Remember that

The domain of a function is the set of all possible values of x

The quadratic functions are continuous and defined for all real values of x.

therefore

The domain of the function f(x) is the interval (-∞,∞)

That means

All real numbers
