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.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
