the form (x, y) is shown below.
{(2,0),(4,0), (6,0), (8,0)}
What is the domain of the function?

Answer 1

{2, 4, 6, 8}

Explanation:

The domain refers to all the possible x values of a function.

Our ordered pairs :

• (2,0)
• (4, 0)
• (6, 0)
• (8, 0)

As they are in the form (x, y), the domain is :

⇒ {2, 4, 6, 8}
