Do you have a calculator with you?

3. AutumnMaybury

yes i do

4. hba

5. AutumnMaybury

:D

6. Aperez

Fine . Then on the top you will see a button that says Y= do U see it? Insert the problem and it will graph it for U :)))

7. AutumnMaybury

How do i graph the inverse though?

9. AutumnMaybury

yeah i need to do an original which is 3x-5 then i need to inverse that

Ohhh Okay I see Wait

12. AutumnMaybury

ok thanks so much

13. Aperez

It's -5x+3 just like rearrange them :D like that sorry this is my attempt tho.

14. AutumnMaybury

so thats the inverse of 3x-5

15. Aperez

yes :D

There's a quick and easy process to finding the inverse for f(x)= 3 x-5 First replace "f(x)" with "y" and now you are left with y=3x-5 ___________________________________________________ The next step will be to switch the "x" and the "y" and you are left with x=3y-5 ______________________________________________________ Now solve for "y" Solving for y means trying to isolate the y on one side of the equation. I won't this since you need to do a little of the work. Can you tell me what you get after solving for "y"?

If the question is just for graphing, all you need to graph the inverse is to find it's image after reflecting about the line y=x. |dw:1358026554530:dw|
