Question

Use complete sentences to describe the relation in terms of a function. F = {(2, -4), (2, 7) (3, 5), (4, -1), (8, 7)}

Answer 1

The relation F is not a function

Explanation:

A relation is a function if and only if for each input value x, there is a single output value y.

If for an input value x there are two or more output values y ​​then the relation is not a function.

In this problem we have the following relationship:

F = {(2, -4), (2, 7) (3, 5), (4, -1), (8, 7)}

Note that for the input value
`x = 2` there are two possible output values:
`y = -4`,
`y = 7`.

Therefore, based on the definition described above, the relation F is not a function
