3.8 is bigger because 2 and 5/6 is like saying 2.833. So, 2.8 < 3.8
Answer: The answer is letter B "No; a range value has two domain values".
For a relationship to be a function, there must be a one-to-one correspondence between the x and y values. For every value of x, there must be only one value for y. So the first set is a function and the second set is not.
Answer:
No; a range value has two domain values.
Step-by-step explanation:
Output has to be unique for all inputs.
Output for -2 is not unique
Step-by-step explanation: It is either B or C
Since
x = −
2
produces
y = 1
and
y = 2
, the relation
(
−
1
, 1
)
,
(
−
2
, 1
)
,
(
−
2
, 2
)
, (
0
, 2
)
is not a function.
The relation is not a function.

No; a range value has two domain values
Step-by-step explanation:
Answer:
From what I can see in the picture, the table is a proportional relationship.
y= 2.5x
Answer:
