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|

Crazy boy [7]

Answer:

The domain is {x:x is a real number}

The range is {y:y is only 4}

Step-by-step explanation:

The domain of the function is the values of x

The range of the function is the values of y

f(x) = 4 is represented graphically by a horizontal line // to x-axis from y = 4

Every point on the this line has different values of x but same value of y

ex: (-1 , 4) , (5 , 4) , ( 0.1 , 4) , ................

So f(x) = 4 is called constant function
