True or false? do the following set of ordered pairs represent a function {(8,,-,,-,9)}

Hi there!

Unfortunately, the set of ordered pairs does NOT represent a function! This is because there are two of the same x values. In a function, there is one input for every output. In this case, there are two of the same inputs. However, there can be two of the same outputs. 
Just to clarify - Not a function

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
