    Graphing rational functions appears as part of A-REI.11 which PARCC has in Algebra I and Algebra II. However F-IF.7d has graphing rational functions as a plus standard. I am a little unclear what grade level graphing rational functions is intended for. Any thoughts?



    I think that students don’t have to actually graph rational functions (or any function) in order to practice problems related to A-REI.11. This standard is much more concerned with the fact that the x-coordinate of the intersection of the graphs is the solution of the corresponding equation. To practice that, the students can just be given the graph ready-made, and they can also graph the functions themselves using a graphing calculator.
