Domain: $x >= 0$ . In interval notation : $[0,oo)$
Range: $y <=8$ In interval notation : $(-oo,8]$

$y= sqrt(1) - sqrt(x) +7 or y= 8-sqrt(x)$

Domain: Under root should be $>=0 :. x>= 0$ ,

Domain: $x >= 0$ . In interval notation : $[0,oo)$

Range: Max $y=8$ , Minimum: $y = -oo$

Range: $y <=8$ In interval notation : $(-oo,8]$

graph{8-x^0.5 [-160, 160, -80, 80]}
