Why plural? There is only one derivative of that function.
Let x+1 = u, so that
m(x) = m{u(x)}, m(u) = 1/u, and
du/dx = 1
Then use the chain rule
dm/dx = dm/du*du/dx
= -1/u^2 = -1/(x+1)^2
Let x+1 = u, so that
m(x) = m{u(x)}, m(u) = 1/u, and
du/dx = 1
Then use the chain rule
dm/dx = dm/du*du/dx
= -1/u^2 = -1/(x+1)^2
