f(x) = x/x
g(x) = 1
so... those are different functions? i don't know how to treat expressions like that.
When expression is not defined for some x=a, but after some algebraic transformations i get expresion defined for x=a ... what happends?
Can i make algebraic transformations on expressions with an unknown number without knowing it's value?
I know can.
But can i do this with epression that is part of a function?
