{(1,94), (2,94), (3,82), (4.74)
is the relation a function

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.

that would be 3•12+6•8+2•7
