Answer:- The set of values assigned to s is called the domain.
Explanation :-
For the given equation y= x+2, x is a independent variable where y is a dependent variable .
The given equation representing a function y=f(x)=x+2
We know that for every function f(x), the set of values assigned to x is called the domain and the set of corresponding outputs y for each value of x is called the range.
