In a question a student was given to find the derivative of the product of two functions `fa n dgdot` The student by mistake thought `(fg)^'=f'g'` for his question `f(x)=x^3` and he got the correct answer. Given that `g(4)=1.` Then which of the following is false? `g(5)=1/8` b. `f^(prime)(x)<0` c.`f(0)<0` d. none of these
