This is the proof for l'hopitals rule in my book:

I don't get why they use the function F to make the proof? It is the saying from it with cauchy mean value theorem that makes the start for the proof but could they not manipulate any function to make this proof work, I mean it looks like they just made up F? And at the end of the proof I don't get why f(a)=g(a)=0
Hope someone could help me out:)
