A small manufacturing company makes and sells x machines each month. The monthly cost C, in dollars, of making x machines is given by C (x) = 2600 + 0.4x^2 . The monthly income I, in dollars, obtained by selling x machines is given by I(x)=150x−0.6x^2 . (a) Show that the companyís monthly profit can be calculated using the quadratic function P(x)=−x^2 +150x−2600.

P(x) = I(x) - C(x) = (150x−0.6x²) - (2600 + 0.4x^2)

profit=selling price-cost price so, selling price is 150x-0.6x^2 cost price is 2600 + 0.4x^2
