Question

Is this a function ? helpppp​

Answer 1

yes

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

Answer 2

yes

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
