Question

find the marginal revenue and marginal profit functions C(x)= 4x; R(x)= 8x-0.001x^2

Answer 1

I believe differentiation is the method used.

Answer 2

please show how answer is found

Answer 3

C'=4

Answer 4

Differentiate 4x. That is the step.

Answer 5

I have that thats the marginal cost I need marginal revenue and profit

Answer 6

do something similar to the revenue function.

Answer 7

R'=8-.002x Marginal revenue

Answer 8

Yes that was C' or marginal cost I see now they did not ask for that. sorry lol.

Answer 9

Marginal Profits. First calculate the profit function.R(x) - C(x) to get P(x) then differentiate for marginal profit.

Answer 10

can I see how to get the answer

Answer 11

P(x)=8x-.001x^2-4x=4x-.001x^2
P'(x) = -.002x+4 or 4-.002x

Answer 12

I believe you would get the same answer if you would of used:
P'=R' - C'

Answer 13

The marginal revenue is 8-x/500 is the correct answer the marginal revuenue how do I get that

Answer 14

can anyone help me
