What's the question

4. Katieann16

Find the equation of the inverse of $f(x)=\frac{ 1 }{ 3 } x + 5$

5. Katieann16

@zepdrix

6. math>philosophy

I would set it up like $y = \frac{1}{3}x + 5$ and then just switch the y and x and solve for y

7. skullpatrol

Do you know what an inverse function is?

8. zepdrix

Katie, you should label your threads appropriately, instead of "HELP PLEASE" lol... XD Anyway, Do you understand what phil was instructing you to do?

9. Katieann16

Phil? & @skullpatrol , i think its f^-1 (x)= 3x-15

10. zepdrix

Looks good! c:

11. skullpatrol

That's the idea.

12. Katieann16

yah but its not the answeer

13. skullpatrol

14. Katieann16

idk not that

hi nincompoop

18. timo86m

Thank you captain obvious

19. math>philosophy

lololol

20. timo86m

cuz nobody asked such a q you flutterer

21. timo86m

@skullpatrol mines is correct i swapped the x and y for last step. she wants it f(x) y in terms of x.

22. timo86m

finding the inverse of f(x). Ye so get the flutter out of here nin

23. math>philosophy

pwnt

24. timo86m

flutter you

25. skullpatrol

PEOPLE, PEOPLE let @Katieann16 talk this is HER question, remember???

26. skullpatrol

Well @Katieann16 any questions?

27. Katieann16

ummm,so my answer is x=3y-15 right?

28. skullpatrol

no

29. timo86m

swap x and y y=3x-15 which is also f(x)=3x-5

30. Katieann16

31. timo86m

yes

32. Katieann16

thank you

33. Katieann16

All of you

34. skullpatrol

Do understand the idea of an inverse?

35. Katieann16

yes

36. skullpatrol

Good job :-)
