add sub rational functions

[joshuagonzalezramirez]

I think there is something important missing in letter j); the non-permissible values. When I was working through the question alone, I found that the NPVs were: x≠ -5, 0, 5 though I am really not sure about the zero as an NPV. Could you tell whether I am right or mistaken? Thanks! Great video, by the way.
