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

Dec 8, 2017

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

#### Explanation:

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

since x has to be $\ge$ 0 ,
the Domain will be [0,$\infty$)
if you see output of the function the maximum value of y is 2.
therefore range of the function is (-$\infty$,2]
