G(x)=(5-x)/(2x-1) f(x)= (x+5)/(2x+1) what is g(f(x))
Elina [12.6K]
\bf \begin{cases}
g(x)=\cfrac{5-x}{2x-1}\\\\
f(x)=\cfrac{x+5}{2x+1}
\end{cases}\qquad g(~~f(x)~~)=\cfrac{5-f(x)}{2[f(x)]+1}
\\\\\\
g(~~f(x)~~)=\cfrac{5-\left(\frac{x+5}{2x+1}  \right)}{2\left(\frac{x+5}{2x+1}  \right)-1}\implies  g(~~f(x)~~)=\cfrac{\frac{5(2x+1)-(x+5)}{2x+1}}{\frac{2x+10}{2x+1}-1}

\bf g(~~f(x)~~)=\cfrac{\frac{10x+5-x-5}{2x+1}}{\frac{2x+10-1(2x+1)}{2x+1}}\implies 
g(~~f(x)~~)=\cfrac{\frac{9x}{2x+1}}{\frac{2x+10-2x-1}{2x+1}}
\\\\\\
g(~~f(x)~~)=\cfrac{\frac{9x}{2x+1}}{\frac{9}{2x+1}}\implies g(~~f(x)~~)=\cfrac{\underline{9} x}{\underline{2x+1}}\cdot \cfrac{\underline{2x+1}}{\underline{9}}
\\\\\\
g(~~f(x)~~)=x

What would the inverse be?
marta [7]
Find the inverse of f(x)=2x-3.

1) replace "f(x)" with "y."   Then y=2x-3.
2) interchange x and y.  Then x=2y-3.                   x+3
3) solve this result for y.  Then 2y=x+3, or   y=----------------
                                                                                  2
                            -1           -1           x+3                        
4) replace y with f   (x):    f    (x) = ---------
                                                           2

This is the procedure, with the answer given.
