**Algebra/Precalculus**

How can I verify that f(x)=(x+3)/(x-2)and g(x)=(2x+3)/(x-1)are inverse functions (i.e. show the process)? Also, how can I solve (g o f)^-1, if f(x)=x+4 and g(x)=2x-5? Thanks!

**Algebra-Functions**

Could you please check my answers and help me with two problems? Determine which two functions are invereses of each other. 1. f(x)=5x, g(x)x/5, h(x)5/x -I got that f(x) and g(x) are invereses of each other 2. f(x)=x-2/(2), g(x)=2x-2, h(x)=x+2/(2) -I got that f(x) and h(x) are...
