dy Write the following function in the form y = f(u) and u = g(x). Then find as a function of x. dx 3 y = + X 6 X Write the given function in the form y = f(u) and u = g(x). Choose the correct answer below. O A. y= f(u) = u and u = g(x) = XN +X - 6 2 O B. y = f(u) = u and u = g(x) = + X 6 2 O c. y= f(u) = u' and u = g(x) = X N + X - 6 3 O D. y= f(u) = us and u = g(x) = XN + X
