Domain would be [0, $oo$ ) and Range would be [-2, $oo$ )

Explanation:

The function would either be y+2= $sqrt x$ or - $sqrtx$ . If y+2= $sqrt x$ is the function, it would represent the upper portion of a horizontal parabola, with its vertex at (0,-2).

Domain would be [0, $oo$ ) and Range would be [-2, $oo$ )
