Question 148556
I need an 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 betwen -12 and +5

f={(0,-11),(1,2),(3,4),(7,0)} is a function


I also need an example of at least 4 ordered pairs that DOES NOT model a function.  The DOMAIN will be any four integers between 0 and +10.  The RANGE will be any four integers between -12 and +5.

f={(0,-11),(1,2),(3,4),(3,9),(7,0)} is not a function
