The question is determine whether each relation is a function. Find the domain and range 4.{(4,5),(1,5),(3,8),(4,6),(10,12)}
bibby
  • bibby
a relation is a function if it has one x for every y. that means we can't have repeated x values. do we?
dayakar
  • dayakar
in other words, each first coordinate (x) is different ,it is called a function
anonymous
  • anonymous
Yes there is so its not a function correct?
dayakar

domain=set of all first co-ordinates

range= set of all second co-ordinates
