Look at this set of ordered pairs: \( \begin{array}{l}(17,-2) \\ (5,0) \\ (17,20) \\ (-7,16) \\ (3,9)\end{array} \) Is this relation a function?

To determine if the given set of ordered pairs represents a function, we need to check if each input (the first element of each ordered pair) is associated with exactly one output (the second element of each ordered pair). Let's list the ordered pairs and their inputs: 1. \( (17, -2) \) - Input: 17 2. \( (5, 0) \) - Input: 5 3. \( (17, 20) \) - Input: 17 4. \( (-7, 16) \) - Input: -7 5. \( (3, 9) \) - Input: 3 Now, we can see that the input 17 appears in two different pairs: \( (17, -2) \) and \( (17, 20) \). This means that the input 17 is associated with two different outputs (-2 and 20). Since a function cannot have the same input associated with more than one output, we conclude that this relation is **not a function**.
