The answer should be number 3

Answer:

Domain {x| x is a real number}; {y| y = 4}.

Step-by-step explanation:

Given : f(x) = 4.

To find : What are the domain and range of the function.

Solution : We have given  f(x) = 4

Domain : The set of all input values for which function is real and defined:

(-∞ , + ∞).

Range : The set of dependent variable on which function is defined.

The range of constant function is always constant.

So, range = 4.

Therefore, Domain {x| x is a real number}; {y| y = 4}.
