Here is the question:
I have posted a link there to this thread so the OP may view my work.The air pollution y(in parts per million) x miles away is given by y+2xy+x^2y=600.?
The air pollution y(in parts per million) x miles away is given by y+2xy+x^2y=600. Find the rate of pollution 10 miles away.
E. None of the above
I have no idea how to do this but it has something to do with derivative because that's what were doing
