Match each given domain of the function f(x)=x/2.5 with its corresponding range.
a. {40,45,50,55,60} b. {52,56,63,67,71} c. {37,46,49,55,57} d. {44,51,59,66,67}

1. {20.8,22.4,25.2,26.8,28.4}
2. {16,18,20,22,24}
3. {17.6,20.4,23.6,26.4,29.2}
4. {14.8,18.4,19.6,22,22.8}

Domain A matches Range 2  because 

40/2.5 = 16 , 45/ 2.5 = 18   and so on  -all 5 work ou.

If you do the same calculations for B, C and D you'll get the correct answers

It looks like Domain B matches Range 1:-  52 / 2.5 =  20.8, 56/2.5 =  22.4  

- I think I can leave you to finish this off .

Coral reefs,temperate grasslands, and kelp forests are all in danger.
