The amount of money a certain company makes can be represented by the graph y = x^2 - 18x - 33 , where x is the quantity produced. What is the smallest quantity at which the company can produce to break even or make a profit?

Look at the zeroes of the quadratic ....this is where y = profit = zero

   using quadratic formula   x = 19.677   or  - 1.677     (see graph below)

     so the need to produce at least 20  to mak a profit ( a positive 'y' value)
