Graph the original function and its inverse f(x)= 3 x-5
|dw:1357917181521:dw|
Do you have a calculator with you?
yes i do
Nice answer.
:D
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 :)))
How do i graph the inverse though?
Inverse as what your saying the the one your doing now?
yeah i need to do an original which is 3x-5 then i need to inverse that

Ohhh Okay I see Wait
ok thanks so much
It's -5x+3 just like rearrange them :D like that sorry this is my attempt tho.
so thats the inverse of 3x-5
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|
