Assignment for Friday, February 27: test 2
The cost function C(x) and its marginal function C'(x), the
revenue function R(x)=px and its marginal function, and the profit
function P(x)=R(x)-C(x), are all important functions that arise
in economics. You must know how these functions are defined and
how to find their marginals. We did examples 5 and 6 about Acrosonic
Loudspeakers in class. You can expect to have to interpret what
your results mean after finding the marginals in a question.
