Question

A function is represented on the graph

Which best represents the domain and range of the function?
Move the correct answer to each box. Each answer may be used more than once. Not all answers will be used.

Answer 1

-4 < x < 6

0 < y < 8

Explanation:

See the attached worksheet. The domain is the range of inputs (x) and the range is the, uh, range of outputs, y. Technically, both answers are incorrect, since the graph clearly shows a solid dot at the extremes of the function. This means that point is also included. So if the dots were exactly on the values noted, each answer should appear as:

-4 ≤ x ≤ 6 and 0 ≤ y ≤ 8

But

Domain: -4 < x < 6

Range: 0 < y < 8

are the closest answers.
