Chapter 8.3, Problem 48SR

To determine

To calculate: To determine whether the relation is a function

Answer to Problem 48SR

The relation is a function

Explanation of Solution

Given information: Relation is $\left\{\left(0,6\right),\left(-3,9\right),\left(4,9\right),\left(2,1\right)\right\}$

Formula Used:

Set of Ordered pairs is function if no two ordered pairs have the same first coordinate with different second coordinates.

Calculation:

Relation is given as follows:

  $\left\{\left(0,6\right),\left(-3,9\right),\left(4,9\right),\left(2,1\right)\right\}$

Here, no two ordered pairs have the same first coordinate with different second coordinates.

Conclusion:

Hence, the relation is function
