What are the domain and range of the function  f(x) = 4? {x|  x  is a real number}; {y|  y  > 0}{x|  x >   4}; {y|  y  > 0}{x|  x  is a real number}; {y|  y  > 4}{x|  x >   4}; {y|  y  > 4}

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}.

$113.42

i hope that is right.
