Question

Determine the range of the following graph:

Answer 1

Step-by-step explanation:

the range of a function is the interval or set of the possible and valid y (functional result) values.

the graph shows me that the produced y values are all between -4 and -9.

so, the range is [-9, -4] (smaller number on the left, larger number on the right). both sides included.

please consider that the excluded end point at (3, -6) does not make any difference, as the y value -6 is produced for 2 more x values (like x=-2). so, the y value -6 is included in the range nevertheless.
