let f(x)=ln(x)x>0 let k(x)= f(g(x))
and m(x)= f(g(x))
a) Find the domain of the function K(x).
b) Find the domain of the function M(x).
c) Find the value of k'(5)

since we don't have a definition for g(x), it gets a bit tough. Also, you have m(x) = k(x). Time to proofread and repost.
All we know is that k'(x) = 1/g(x) * g'(x)
