3. A function is defined by the set of ordered pairs {(2,4),(6,2).(3,1)(7,5)}. Which of the
following values is not in the domain of the function?
(1) 7
(3) 3
(2) 6
(4) 4

Respuesta :

The domain includes all values of x.

The ordered pairs show values of both y and x, with x being first (x,y)

All the values of x shown (aka the domain) are: 2,6,3,7

Therefore, 4 is not in the domain
