Weird derivative question? stewart calculus 3.3 #54?
a) what does it mean to say that f(20)=10,000 and f'(20)=-350?
b) find R'(20) and interpret your answer.
I have know idea of how to do this question.
I know how to take derivatives and stuff.
this question is asked after the book discussed the product and quotient rules. antiderivatives are not handled yet.
