Homework Equations
5a: ln((x*(x-2))/(x2-4))
ln((x22x)/(x2-4))
ln(x/(x+2)) <-- the answer (i think)
The Attempt at a Solution
Im not completely sure about that answer in 5a so could somebody check that? also I'am having truble with b:
f(x)--> y=ln(x/(x+2))
f-1(x)--> x=ln(y/(y+2))
ex=y/(y+2)
then i get in truble...
