## anonymous one year ago inverse of the function f(x)=3x+9? would this be : f(x)=x-9/3 ?

1. jim_thompson5910

do you mean $\Large x - \frac{9}{3}$ OR $\Large \frac{x-9}{3}$ ??

2. anonymous

the second one

3. jim_thompson5910

you have the correct inverse function, you would write it like this $\Large f^{-1}(x) = \frac{x-9}{3}$
