Question

Create a list of 4 ordered pairs: (For example) { (1,3) (2, 6) (3, 9) (4, 12)}

●What is the domain of the relation you created?
●What is the range?
●What is the inverse?
●Is it a function? Why?

Answer 1

(1,2), (2,3) , (3,4), (4,5)

domain (x values) are : { 1,2,3,4 }
range (y values) are : { 2,3,4,5 }
inverse : (2,1), (3,2), (4,3), (5,4)
Is it a function : yes, it is a function because it has no repeating x values
