Question

The cost (in dollars) of manufacturing x items is given by: c(x) = x3 - 7x2 15x.What is the cost of manufacturing 11 items?

Answer 1

Answer:

809$

Explanation:

Let's substitute x = 11 into the function

c(11)=(11)^3−7(11)^2+15(11)

c(11)=1331−7×121+15×11

c(11)=1331−847+165

c(11)=644+165

c(11)=809

So, the cost of manufacturing 11 items is $809.
