Square root functions domain have to be set greater than or equal to zero, so we can set x+4 greater than or equal to zero. [tex]x + 4 \geqslant 0 \\ x \geqslant - 4 \\ \\ [/tex] [-4, + infinity)
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain Domain: [-4,∞),{x | x ≥ -4} Range: [0,∞),{y | y ≥ 0}
