Question 52914: determine which of the following relations is also a function.if the given relation ia a function then indicate the domain and range of the function using set notion such as={2,5,6,10,11},range={8,4,1,1,0}
1.{(-1,10),(3,7),(4,5),(-6,3),(3,-6),(1,-10),(9,-4)}
2.{(-2,9),(10,9),(-6,6),(8,-10),(7,-1),(-2,-5)}
3.{(-10,-2),(-1,10),(6,-9),(5,10),(-7,8)(5,-6),(-3,7),(1,-9)}
4.{(8,8),(3,-2),(-6,-3),(-4,-1),(_4,4),(1,-6),(9,-2)}

You can put this solution on YOUR website! determine which of the following relations is also a function.if the given relation ia a function then indicate the domain and range of the function using set notion such as={2,5,6,10,11},range={8,4,1,1,0}
FOR THESE RELATIONS TO BE FUNCTIONS,
SAME FIRST ELEMENT SHOULD NOT HAVE 2 DIFFERENT IMAGES
1.{(-1,10),(3,7),(4,5),(-6,3),(3,-6),(1,-10),(9,-4)}...
NO...3 HAS 2 IMAGES
2.{(-2,9),(10,9),(-6,6),(8,-10),(7,-1),(-2,-5)}
NO -2 HAS 2 IMAGES
3.{(-10,-2),(-1,10),(6,-9),(5,10),(-7,8)(5,-6),(-3,7),(1,-9)}
5 HAS 2 IMAGES
4.{(8,8),(3,-2),(-6,-3),(-4,-1),(_4,4),(1,-6),(9,-2)}
-4 HAS 2 IMAGES??OR IS IT A TYPING MISTAKE..IF IT IS -4 AND +4 IN THE 2 PLACES ,THEN THIS IS A FUNCTION
