Question

What is the domain of the relation graphed below?

Answer 1

Answer: Choice C)
`\text{Domain: }\left\ \ -4 \le x \le 4\right\`

This is because the left-most point occurs when x = -4, and the right-most point is when x = 4. We can have any x value in between these endpoints. The domain is the set of all allowed x inputs.
