Answer: [-9, 7)

Step-by-step explanation:

The range is the set of possible y outputs of a function. We look at the y coordinates of the points on this diagonal line.

The lowest we can go is y = -9. This endpoint is included because of the closed filled in circle. In contrast, the open hole at the top means y = 7 is not included.

The range spans from -9 to 7. We include -9 but exclude 7.

We write this as the inequality
-9 \le y < 7 and then that condenses to the interval notation [-9, 7)

Use a square bracket to include the endpoint -9. Use a parenthesis to exclude the endpoint 7.
