My task is to give your own example of a function using a set of at least 4 ordered pairs. The DOMAIN will be any four integers between 0 and +10. The RANGE will be any four integers between -12 and 5. Then give an example of 4 ordered pairs that don't model a function.

My example of a function is {(3,1) (5,-9) (7,2) (10,5)}, is this correct?

Thanks!
