Mathematics
1 answer:
svlad2 [7]2 years ago
6 0

Answer:

FIRST OPTION.

SECOND OPTION.

FOURTH OPTION.

Step-by-step explanation:

By definition, a relation is a function if an only if each input value ( each x- value) has only one output value (y-value).

Based on this you can identify that:

1. The relation (8,7), (7,8), (6,5), (5,6)  is a function.

2. The relation (-2,7), (-3,9), (-5,9), (-8,11) is a function.

3. The relation (6,-6), (-3,12), (6,-1), (-8,13) is not a function, because the input value 6 has two different output values:

x=6,y=-6\\\\x=6,y=-1

4. The first table represents a function.

5. The second table does not represent a function, because the input value 0 has two different output values:

x=0,y=0.5\\\\x=0,y=2
