Question

f(x)=x/x-2 inverse function?

Answer 1

Answer 2

lets start with the definition, the function is called the inverse function of because it "reverses" ; that is to say .
so knowing this, we reverse the function,

so we solve x/x-2=y for x,
x=-2y/-y+1 ; where y does not equal 1,
substitute y with x;
-2x/-x+1

Answer 3

That's true if and only if we're referring f(x)=x/(x-2) not f(x)= (x/x) -2 something @cinnamonbun that should be made explicit.
