1. If a rule defining a function is given but the domain has not been specified explicitly, then the largest set which makes the rule meaningful is understood.
2. This set is denoted by D_f for the rule y=f (x) and is called the natural domain of the function.
3. The function given by the rule f(x) =makes sense if its denominator is not zero.
4. For the function given by the rule f(x) =, x–1≠0 should be satisfied.
