the table represents a function.
select all of the values that are in the range:

x	y
7	9
9	9
12	10
21	9

show your work here
□ 7 □ 9
□ 10 □ 12
□ 21

Explanation:

Step1: Recall range definition

The range of a function is the set of all output (y) values.

Step2: Identify y - values

From the table, the y - values are 9, 9, 10, 9. So the unique y - values (range elements) are 9 and 10.

Step3: Match with options

Check which of the given options (7, 9, 10, 12, 21) are in the range (y - values). 9 and 10 are the y - values, so they are in the range.

Answer:

9, 10
