Depends greatly on the type of function.
Some things to keep in mind:
1.) the value of the denominator of a fraction cannot be zero
2.) the inside of an even root cannot be less than zero
3. The argument of a logarithmic function must be greater than zero
4. Plus many more other rules and such
But a simpler explanation, just find out what values x can be for the given function, and what y can be.
The x values make up the domain, the y, the range
Graphs are helpful
Hope this helps!
