This is a graph of $\displaystyle{f{{\left({x}\right)}}}=-{3}-\sqrt{{x}}\usepackage{cmbright}\Huge\$ . Subtracting 3 on the inside of the radical moves the graph to the right. Subtracting 3 on the outside moves the graph down from the graph of $\displaystyle-\sqrt{{{x}}}\usepackage{cmbright}\Huge\$ .
