Look at this set of ordered pairs: \[ \begin{array}{l}(-18,15) \\ (-17,3) \\ (5,3) \\ (6,-3) \\ (10,3)\end{array} \] Is this relation a function? yes no

To determine if this relation is a function, we need to check if each input (the first number in each ordered pair) maps to exactly one output (the second number). In this case, the inputs are -18, -17, 5, 6, and 10, all of which map to unique outputs (15, 3, 3, -3, and 3 respectively). The input 5 has the same output as the input -17, but since each input has only one corresponding output and isn't repeated with a different partner, this relation satisfies the definition of a function. So, yes, this relation is a function! For more clarity, remember that functions can have the same output for different inputs. What matters is that each input only corresponds to one output. So while we see the output 3 showing up multiple times for different inputs, it doesn’t disqualify the relation from being a function. It still checks out!
