Question

What is the domain and range?

Answer 1

Hello from MrBillDoesMath!

Answer:

Domain = { 5. 10. 15. 20}

Range =  -3,-1,1,3} .

Discussion:

The domain is the set of all "x" values, that is  { 5. 10. 15. 20} and the range is (-3,-1,1,3} . The arrows in the diagram show the mapping between the domain and the range. For examples, 5 -> 1 ( "x value 5 is mapped to y value 1"),        10 ->3, 15 ->-3, and 20 -> -2

Thank you,

MrB
