How do you graph #y=-2sqrtx+2#, compare to the parent graph, and state the domain and range?

this graph is only for a real valued function , which means x cannot take negative values


graph{-2*sqrt(x) + 2 [-10, 10, -5, 5]}

since x has to be #>=# 0 ,
the Domain will be [0,#oo#)
if you see output of the function the maximum value of y is 2.
therefore range of the function is (-#oo#,2]
