Question 1023804

Solve the problem and graph:

Suppose that a cost function for the production of a particular item is given by the equation C(x) =2x^2-320x+12,920, where x represents the number of items.  How many items should be produced to minimize the cost?
<pre>Minimum cost occurs where {{{x = - b/a}}}, or at: {{{x = - - 320/(2 * 2)}}}, or: {{{x = 320/4}}}, or: {{{x = 80}}}
Number of items to produce to MINIMIZE cost: {{{highlight_green(80)}}}
