(c) Assume f (x) and 9(3) are differentiable for all real numbers and f (3:) + 9(3) 75 0. Find an expression for i ( f ($19M ) dm f (m) + 9(3) in terms of f (9:), f'(m), 9(x), 9"(m). In your solution, please state the differentiation rules that are being used and explain why those rules can be applied. NOTE: Do not pick particular functions x) and 9(a). You should treat them as unknown functions
