Question

Look at this set of ordered pairs:

(20, 14)
(2, 20)
(2, 6)

Is this relation a function?

Answer 1

To determine if a relation is a function, we need to check if each input (the first element of each ordered pair) maps to exactly one output (the second element of each ordered pair).

Looking at the ordered pairs you provided:

1. (20, 14)
2. (2, 20)
3. (2, 6)

We see that the input "2" appears in two different pairs: (2, 20) and (2, 6). Since the input "2" maps to two different outputs (20 and 6), this means that the relation is not a function.

In summary, the relation is not a function because the input 2 has multiple outputs.
