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?

The zeroes of y = x^2 - 18x - 33  using the quadratic formula,   are x = 9 +- sqrt 114

   the POSITIVE root shows where the bowl shaped parabola becomes POSITIVE    9 + sqrt 114 = 19.67     ~~ 20 units will start showing a profit
