PIf f is the focal length of a convex lens and an object is placed at a distance p from the lens, then its image will be at a distance q from the lens
where f, p, and q are related by the lens equation

f
What is the rate of change of p with respect to q if q = 6 and f = 8? (Make sure you have the correct sign for the rate.)
