Lala Member since:October 08, 2010Total points:395 (Level 2)the profit in dollars from the sale of x thousand compact disc players is P(x)= x^3- 3x^2+ 8x+5
find the marginal profit when the value of x is 3Answer Question
by bill Member since:March 30, 2008Total points:5,708 (Level 5)jsut take the first derivative to find marginal profit which would be
p'(x)=3x^2-6x+8+0
then set all of the x's= to 3
p'(3)=3(3)^2-6(3)+8
p'(3)=9^2-18+8
p'(3)=81-18+8
p'(3)=71
