Select all true statements about the derivatives of f and g. There may be more than one correct answer. f(x) A. g (x) f' (x) - f(x)8' (x) g (x) (8(x)) 2 B. (f (x)g(x))' = f' (x)g' (x). ac. (f (x)g(x))' = f'(x)g(x)+f(x)g' (x). D. f(x) f' (x) g(x) g' (x) f(x) E. = f(x)8' (x) - 8(x)f'(x) g(x (8' (x) ) 2
