# For the revenue function given by R ( x ) = 2800 x + 8 x 2 − x 3 (a) find the maximum average revenue.(b) show that R ¯ ( x ) attains its maximum at an x-value where R ¯ ( x ) = M R ¯ .

(a)

To determine

To calculate: The maximum average revenue for the function R(x)=2800x+8x2x3.

Explanation

Given Information:

The provided revenue function is:

R(x)=2800x+8x2x3

Formula used:

If f(x) and g(x) are two differentiable functions then by the property of derivative:

ddx(f(x)+g(x))=ddxf(x)+ddxg(x)

And

ddxxn=nxn1

Where n is a constant and x is the variable.

And the average revenue is defined as:

R¯(x)=R(x)x

Where R(x) is the revenue function.

Calculation:

Average revenue is given as:

R¯(x)=R(x)x=2800x+8x2x3x=2800+8xx2

The absolute maxima and absolute minima will occur only at the critical points. To calculate the critical points of the revenue function, find the first derivative of the function:

R¯(x)=2800+8xx2ddx(R¯)=ddx(2800+8xx2)

Use ddx(f(

(b)

To determine

To prove: The revenue function R¯(x) attains its maximum at an x value where R¯(x)=(MR)
