Question
my question is Question D :graph, break-even points and x-intercept
The total cost and the total revenue (in dollars) for the production and sale of x ski jackets are given by C(x) = 20x +23,680 and
R(x) = 200x - 0.2x for 0sxs1000.
(A)
Find the value of x where the graph of R(x) has a horizontal tangent line.
(В)
Find the profit function P(x).
(C)
Find the value of x where the graph of P(x) has a horizontal tangent line.
(D)
Graph C(x), R(x), and P(x) on the same coordinate system for 0sxs 1000. Find the break-even points. Find the x-intercepts of
the graph of P(x).
(A) R(x) has a horizontal tangent line at x = 500
(B) The profit function P(x)=- 0.2x + 180x- 23680
(C) P(x) has a horizontal tangent line at x= 450
(D) Choose the correct graph of C(x), R(x), and P(x) graphed together.
