domain is the x values that we can use range is the y values we can use remember, open circle is like < and > but filled in circle is ≤ and ≥ x is left right y is up down so 68. a. we see we have x=-2, x=-1, x=2 and y=0, y=1, y=-1 domain is D={-2,-1,2} range is R={-1,0,1} b. x goes from -1 to 1, not including -1 range is from 2 to -1, not including 2 domain is D={x|-1-1} range is R={y|y>-1} d. domain and range is all real numbers
