Question

Look at this table:

X
1
12
16
3
14
9
128
4
19
10
-18
Is this relation a function?

Answer 1

To determine whether the relation represented in the given table is a function, we need to check whether each input (x-value) in the table is associated with a unique output (y-value).

We can see that the input value "12" has two different output values, "16" and "19". This means that the relation is not a function since the same input is associated with multiple outputs.

Therefore, the relation represented in the given table is not a function.
