Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!

2. anonymous

from chapter 12

3. immanuelv

f^-1 (x) = (x-4 )/ (3)

4. anonymous

$f \left( x \right)=3x+4$

5. anonymous

how will i graph that

6. anonymous

look at it like y=mx+b or y=3x+4

7. anonymous

i kno...but like can you hlep me find the Points i can Use to graph

8. anonymous

put your pincle on the y intercept of 4 move up 3 boxes and to the right 1

9. anonymous

its a chapter 12 problem i need to graph tht and the inverse

10. immanuelv

i told u the inverse

11. anonymous

i kno....but i need to get the Normal graph Correct....

12. immanuelv

it is $1±(\sqrt(3-x))/(\sqrt(2))$

13. anonymous

is the square root on the 3 only???

14. immanuelv

it is the answer for f(x)= -2(x+1)^2 +3

15. immanuelv

and the square root is for the whole thing!

16. anonymous

ok

17. immanuelv

square root of 3-x

18. anonymous

kk

19. immanuelv

:)

20. immanuelv

hope it helped!

21. anonymous

it did but i need to show my work...its a damn Test

22. immanuelv

switch x and the y then solve for y again

23. anonymous

lol

24. anonymous

can you help me with my whole test???

25. immanuelv

for 5 min... gotta sleep!

26. immanuelv

so what is the question

27. anonymous

there are alot more ..im on 1B

28. immanuelv

lol... but i have a semester exam tomorrow.... so hurry.

29. anonymous

ohhhh.....well im doin a Take home test rite now

30. immanuelv

k

31. anonymous

can you tell me the Point i would be using if i used 2, 1, 0, -1, -2

32. anonymous

and those numbers were x

33. immanuelv

??

34. anonymous

like in the Equation you gave me

35. anonymous

but put those numbers one by one for X and whats the answer everytime

36. immanuelv

for the equation i gave you?

37. anonymous

yea...the inverse

38. anonymous

for thise 1±((√3−x))/((√2))

39. anonymous

can you tell me what the answer is if you plug the 5numbers i told you

40. immanuelv

2= 1.707 and .2928 1= 2 and 0 0= 2.225 and -.2247 -1= 2.414 and -.414 -2 = 2.581 and -.581

41. immanuelv

42. immanuelv

its 64

43. anonymous

huh?

44. immanuelv

sorry wrong post!

45. anonymous

whats the inverse of 4^x

46. immanuelv

(log x)/ (log 4)

47. anonymous

no its f(x)=4^x...i need inverse of that

48. immanuelv

it is its inverse!

49. anonymous

ok

50. anonymous

$f(x) = 4^x$$f(f^{-1}(x)) = x\implies x = 4^{f^{-1}(x)}$$\implies ln\ x = f^{-1}(x)( ln\ 4)$$\implies f^{-1}(x) = {ln\ x \over ln\ 4}$

51. immanuelv

i was right :)
