The profit (P), in dollars, for a company is modeled by the funtion P=-750x^2+15,000x, where x is the number of items produced. For which values of x will the company losr money?

Answer 1

you want where P < 0

P(x) = 750x(20-x)
You know that P=0 when x=0 or 20

Since the graph is a parabola opening downward, P>0 between the roots.

So, P<0 if x>20
