Question

Find the marginal cost, marginal revenue, and marginal profit functions.
C(x) = 6x; R(x) = 9x − 0.001x^2. And find all values of x for which the marginal profit is zero.

Answer 1

We're using derivatives. I got the answer figured out for though nvmd. c(x)=6 R(x)= 9-.002x and p(x)= 3-0.002x and then p(x)=0.

Answer 2

do one thing
0.001x^2 -3x = 0
x^2 - 3000x = 0
x(x-3000) = 0
therefore x = 0 or, x = 3000
so ur answer is either 0 or, 3000

Answer 3

so u got the answer or not
