Given:
The relation is
{(1,94), (2,94), (3,82), (4,74)}
To find:
Whether the given relation is a function or not.
Solution:
A relation is called function, if there exist unique y-value or output value for each x-value or input value.
We have,
{(1,94), (2,94), (3,82), (4,74)}
Here, each input has unique output value because there is no value of x for which the relation has more than 1 distinct values.
Therefore, the given relation is a function.
