X= {(2, 3), (2, 4), (2, 5), (2, 6)} the domain of x is

Domain: {2}

Step-by-step explanation:

1. By definition, the domain is the input value, this means that it is the x-value of a function.

2. Therefore, keeping the definition above on mind, you have that the domain of x is the x-value of each ordered pair.

3. Then, given x = {(2, 3), (2, 4), (2, 5), (2, 6)}, you can see that x-value of each ordered pair is 2. Therefore, you can conclude that the domain of x is:

Domain:{2}
