Question

3
select the correct answer from each drop-down menu.
look at the tables of values below.
data set 1

x	y
-2	6
0	6
1	4
3	2
5	0

data set 2

x	y
1	-2
3	2
3	0
5	8
7	5

data set □ is not a function, while data set □ is a function.
to turn the data set that is not a function into a function, the point □ can be changed so that the x-value is not equal to □.
reset next

Explanation:

Step1: Check Data Set 1 for function

Each x-value (-2,0,1,3,5) has unique y-value. So Data Set1 is function.

Step2: Check Data Set 2 for function

x=3 has two y-values (2,0). So Data Set2 is not function.

Step3: Fix Data Set2

Change (3,0) to make x≠3. Thus, fix the duplicate x=3.

Answer:

Data set 2 is not a function, while data set 1 is a function. To turn the data set that is not a function into a function, the point (3,0) can be changed so that the x-value is not equal to 3.
