Prove if the given functions are inverses by evaluating the composition f(h(x)) or h(f(x)) g(x) = -(4/-x-3) +1 f(x)= (3/-x-1) -2 How do we go about once we for example plug in the first expression into x in the second expression, in terms of what to do ex...

oh. sorry, what exactly happened at the “swap variables and solve for x” step? How did you get (7-3x)/(x-1)
