Answer by tutorcecilia(2152)   (Show Source):
You can put this solution on YOUR website! f(x) = sqrt(2-x)
For radicals, x must be greater than or equal to zero so,2-x>=0
Solving for the x-values:
-x>=-2
x<=2
So, the domain is x<=2
The range is y>=0
.
Some of the points are (1, 1)(2, 0)(-2, 2)and (-7, 3)
