mhchen · Answer

A number is part of the domain of the equation, if it gives an output.

For your equation, x^2 - 6x + 1, putting in any real number will give an output.

btw for an equation with something like $$y = \sqrt{x}$$
The domain would be numbers greater or equal to 0, because if you put negative numbers in x, it won't give a real output.
