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}

Respuesta :

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 .

Answer:

1. {20.8,22.4,25.2,26.8,28.4}  B. {52,56,63,67,71}  

2. {16,18,20,22,24}  A. {40,45,50,55,60}

3. {17.6,20.4,23.6,26.4,29.2}  D. {44,51,59,66,67}

4. {14.8,18.4,19.6,22,22.8}  D. {44,51,59,66,67}

Step-by-step explanation:

f(x)=x/2.5

52/2.5=20.8
