Yes, it does. Because these points do respect the "law" that for each "x" there is only one "y" that corresponds to it

Can you help me to do this please?Finding the inverse of each function

marusya05 [52]

Let

$y=-\frac{3}{x+1}+2$

Find the equation in terms of y in the form x = f(y).

$\begin{gathered} y-2=\frac{-3}{x+1} \\ x+1=\frac{-3}{y-2} \\ x=\frac{-3}{y-2}-1 \end{gathered}$

Replace y by x in the right hand side, which will be the required inverse of the function.

$g^{-1}(x)=-\frac{3}{x-2}-1$
