Given that $f(x)=\sqrt[\phantom{2}]{g(x)}+1,$ and $g(x)$ is a linear function of form $y=mx+b,$ the domain of $f(x)$ is set of all $x$ such that

$[$Select$]$ nge of $f(x)$ is

$x$ is greater than or equal to zero $g(x)$ is greater than or equal to zero $x$ is greater than $1g(x)$ is greater than zero
