Question

Given f(x)=x-5/3, solve for f1(3)

-1
14
18
21

Answer 1

does that say \(f^{-1}(3)\)?

Answer 2

yes it does

Answer 3

Yes

Answer 4

as always replace f(x) with y
switch y and x
solve for y our new y

Answer 5

\(y=x-\frac{5}{3}\longrightarrow x=y-\frac{5}{3}\\\)

Answer 6

Nicely done, Bibby.

Answer 7

thanks buddy

Answer 8

oh shoot, I just realized you meant \(\frac{x-5}{3}\)

Answer 9

Formatting is very important when asking for help.

Answer 10

\[f(x)=\frac{ x-5 }{ 3 }\]
This is what the equation so if I switch them it would look like:
\[
Correct?

Answer 11

mhm
\(y=\frac{x-5}{3}\longrightarrow x=\frac{y-5}{3}\)

Answer 12

It messed up my equation -.-

Answer 13

looool

Answer 14

did you solve for the new y'?

Answer 15

I'm working on solving it lol

Answer 16
