You could use my polynomial toolkit to do this quite easily.
Get the file "poly.tns" from the Google site and drop it into MyLib.
Then
1. In a Calculator page, run poly\pvar("x")
This lets you enter functions without the need for "quotes".
2. Just run poly\xpress(f1(x)), then poly\xpress(f2(x)), etc
As long as your functions are polynomials they will be nicely
displayed.
