The domain of both $f(x) = 2x - 5$ and $g(x) = 6x - 3$ is all real numbers, $(-\infty, \infty)$, because there are no restrictions like division by zero or square roots of negative numbers. Therefore, the domain of their difference, $(f - g)(x)$, is also all real numbers.

Find the Specified Domain (f−g)(x)( f - g ) ( x )(f−g)(x)
