To find the inverse: Replace f(x) with y Switch x's and y's, so put x where y is and y where x originally was. Solve for y Replace y with f^-1(x)

substitute F(x) with y and make x the subject of the equation. like so \[Y= \frac{ 3 }{ X+1 }\] Now solve it. Y(X+1)= 3 Yx +Y = 3 Yx= 3+y \[x=\frac{ 3+y }{ y }\] now replace the y's with xs and replace x with f(x)' and there you go you have your inverse

Now we can factor out the x |dw:1447486730939:dw| I mean you could've just cross multiplied but it's ok can you finish from here

replace x with f^(-1)(x) and replace f(x) with x. and then re-arrange the equation for f^(-1)x
