Question

For the following exercises, determine whether each of the following relations is a function.

1. y = 2x + 8

Answer 1

The relation y=2x+8 is a function because the two different output values of the function have the one unique input value.

Explanation:

The given relation is y=2x+8.

It is required to determine the relation is a function.

This solution can be obtained by using the concept of function. First write the given relation y=2x+8 and determine whether the given relation is a function.

Step 1 of 1

The given relation is y=2x+8.

This relation shows that the two different output values of the function have one unique input value and this relation is a linear function.

Hence, the relation is a function.
