Answer 1

doamin is all possible values of inputs like x that a function can take as independant variable wheras the range is the values of outputs like y that is dependant variable.

Answer 2

You need to apply this to a particular equation since Domain just tells you what x values are possible for a particular equation and Range just tells you what y values are possible for a particular equation. You are just writing general instructions.
