weird derivative question? stewart calculus 3.3 #54?
q=f(p)
R(p)=pf(p)
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.

R'(p) = p f'(p) + f(p) (1)
R'(20) = 20 f'(20) + f(20) = 20 (-350) + 10000 = 3000
