Question

Is the domain of the following points?43, 7}{-3, 3, 7){-7,3,7}{-7, -3,3,7)

Answer 1

`\text{Domain: }\lbrace-3,3,7\rbrace`

Explanation:

The domain of a set of ordered pairs is the set of the first number in every pair (which are the x-coordinate), then, for the points of the graph above:

A(-3,7)

B(3,7)

C(7,3)

D(-3,-7)

Therefore, its domain would be:

`\text{Domain: }\lbrace-3,3,7\rbrace`
