Question

Which inequality best represents the domain of the part shown?

F. All real numbers
G. All real numbers greater than -6 and less than 8
H. All real numbers greater than or equal to -6 and less than 8
J.All real numbers greater than -3 and less than or equal to 6

Answer 1

H

Explanation:

Hello!

An inequality is easy to read if we know how to read it. Domain is the x values that the line goes through.

When a dark closed circle is on a graph, it means that number counts as apart of domain and range.

-6 is circled, which means in the graph, -6 is apart of the domain.

If a open closed circle is on a graph, it means that the number is skipped in the domain and range.

8 is open, which means 7.9999999999 is a valid domain and 8.0000001 (and any examples) are valid, but 8 is not.

This helps us conclude that H is the only possible answer.
