Question

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

Answer 1

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 `>=` 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]
