#### Answer

Domain: (-5, $\infty$) Range: [-9, $\infty$)

#### Work Step by Step

To find the domain, examine where the inputs lie on the plane. The inputs are continuous after value on -5 on the x-axis, therefore, when written in interval notation the domain is (-5, $\infty$). To find the range, examine where the outputs lie on the plane. The lowest y-axis value is -9 and the outputs are continuous from then on, making the range [-9, $\infty$) in interval notation.
