Unit G Summary Question #10 Range of Rational Functions

10. While the domain of a rational function depends on DIVAH, what do you think the range of a rational function depends on? Give an example.

 The range is quite different than the DIVAH because it depends on a different axis. The range of a rational function depends on the horizantal asymptote because it uses the y- values that are above and below the. Just like DIVAH uses the x- values the range of a rational function uses the y- values. For example if you have a vertical asymptote  with x=-1 and x=2 the domain would be the + and the - vertically, NOT HORIZONTALLY. The points would be written as (2,2),(2,4),(-1,2),(-1,6).
