dy Write the following function in the form y = f(u) and u = g(x). Then find - as a function of x dx y = 3x- Write the given function in the form y = flu) and u = g(x). Choose the correct answer below. N O A. y= f(u) = u and u= g(x) =-+3x 2 O B. y= f(u) = u and u= g(x) =-+3x - 4 X 2 O C. y= f(u) = u and u = g(x) =- O D. y= f(u) = u and u = g(x) = * + 3 x - 4 dy dx Find - as a function of x. dy dx
