Jenny is running in a charity event. One donor is paying an initial amount of $20.00 plus an extra $5.00 for every mile that jenny runs. A. Write a function D9x) for the total donation for x miles run.
B. Find the inverse function.
C. What do x and D-1(x) represent in the context of the inverse function.

Here are all the answers for the previous question you asked with the worksheet it said you deleted the question so I put it all on this one.

1. (1,-2), (0,-5), (-1,-8), (2,-11)

2.(5,3), (8,4), (11,5), (14,6)

3.(11,5), (6,1), (1,-3), (-4,-7)

4.(3,0), (3,2), (3,4), (3,6)

5-6.   I can't see the number on the graph to well so maybe try making another question and send a better picture of the graphs

8. (x)=+

9.(x)=-

10. (x)=2x+

11. (x)=-

12. (x)=-6

13. (x)=+

14. (x)=+6

15. (x)=+

16. (x)=-5x+12

17. (x)=+8

18. (x)=-2x-5

19. (x)=-

20.

a. D(x)=5x+20

b.(x)=-4

c. Every mile that Jenny runs
