Market research indicates that consumers will buy x thousands of units of a particular kind of coffee markers when the unit price is: p(x)=-0.27x + 51 dollars. The cost of producing the x thousands units is C(x)=2.23x^2 + 3.5x +85  A. How much revenues R(x) and profit P(x) are obtained from producing x thousands of units (coffee markers)?  B. For what values of x is production of the coffee marker profitable?  Note: For part b of this question, please provide a detailed explanation and show your work

If f(x)= x^2 − 4x − 1  find the following. (a) f(x+a) =  (b) f(a) = (c) f(x+a)−f(a) = Note x^2 is x square minus 4x-1
