A small business owner wanted to maximize his profits, so he gathered data and developed the mathematical function P(x) = - 2x ^ 3 + 10x ^ 2 - 8x + 12 In this function, P is the business's monthly profit in thousands of dollars, and x is the number of employees. Use a calculator to find the number of employees needed for the profit to be at a maximum. You'll have to limit the domain to x >= 0 , since a negative number of employees makes no sense. Round your answer to a whole number. (Hint: Adjust the range of x and y-values to Xmin= 0 , Xmax = 10, Y min = - 100 Y max = 100 )
