So you should just find the derivative?
P = (X^4 - 2)^2
P = x^8 - 4x^4 + 4
dP/dx = 8x^7 - 16x^3
8x^7 - 16x^3 = 8x^3(x^4 - 2)
I dont know if i understood you perfectly, so if this isnt right, please excuse me ok?
let the demand for child car sets be given by p=(x^4 - 2)^2, where x is the number of seats demanded and p is the price in dollars. find the marginal revenue product if x= 2n, where n is employees. factor final answer.
