Answer:
yes
Step-by-step explanation:
In order to be a function, x values should not be repeated.
For example. (0,2) and (2, 2) would work.
(0,2) and (0,8) would not because there are two values for 0.
In this case, each x-value (0, 2, 7, and 9) are only used once so it is a function
Answer:
yes
Step-by-step explanation:
For this relation to be a function
Each value of x from the domain ( values on left ) must map to exactly one value of y in the range ( values on right )
Here
0 → 11
2 → 9
7 → 4
9 → 2
This is the case here thus represents a function
