Determine where the given function is concave up and where it is
concave down.
f(x)= 2x^3-6x^2-90x
Find the maximum profit and the number of units that must be
produced and sold in order to yield the maximum profit. Assume
that revenue, R(x), and cost, C(x), of producing x units are in
dollars
R(x)=50x-0.1^2, C(x)=4x+10
Find the number of units that must be produced and sold in order
to yield the maximum profit, given the equations below for revenue
and cost....
