If the domain of the function f = {(x, y) | 2x + y = 7} is {1, 2, 3}, what is the range?

The range of the function is {1,3,5}.

Step-by-step explanation:

The function is defined as

The set of all possible inputs is called domain and the set of output is called range.

In other words the possible values of x are elements of domain and the values of y are the elements of range.

Since the domain is {1,2,3} and the function is

Put x=1

Put x=2

Put x=3

Since the possible values of y are 5,3 and 1, therefore the range of the function is {1,3,5}

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
