Oh thanks so much Jomo you have saved me. I used the quotient rule because it was a fraction. I'm a noob to the rules. Which rule would you recommend I use?The first part looks fine.
In the 2nd part the fourth line from the bottom has a wrong sign. Did you answer all part of b?
What about part c?
Why on earth would you use the quotient rule to find that derivative?
Even a more clear wording of what the question is asking me to do would helpAll good I've solved all of part b. Got Q^2 for the derivative. No idea how to go about part c though. Anybody able to help?
What is the value of P when Q>100 (for the given demand function)?I'm really lost as to waht pa

If y =kf(x), then y'=k*f'(x). Example: y= 3x^2, then y'= 3*2x=6x. I suspect that you knew that one. Just note that y= x3/7 = (1/7)x3. So y' = (1/7)*3x2 = (3/7)x2.
