for the first, plug in each of the x values, the resulting y values are your range
e.g.
if x = -2 , y = 1
if x = 0 , y = 3
....
the range is {1,3, ....}
for the given range , plug in each of the values for y and evaluate x,
the resulting values are your domain.
1.
y=-x+3
If the domain is {-2,0,3,6}, find the range.
If the range is{-5,1,4,21}, find the domain.
