The domain is all values of x (without repetition)
The range is all values of y (without repetition)

Do you have graph paper? 
If not, do you have geogebra on your computer?

I have a couple graphs to choose from on my answers

mathteacher1729 · Answer

Can you tell which graph is correct?  In other words, do you know how to plot points?

anonymous · Answer

domain is... -1, -1/2, 3/2, 2.
range is.. 1/2, -1, 0, 3/2
Right?

mathteacher1729 · Answer

All you have to do is plot the four points:

(-1,1/2)
(-1/2,-1)
(3/2,0) and 
(2,3/2)


Can you plot those?
