A manufacturer sells video games with the following cost and revenue functions (in dollars), where x is the number of games sold. Determine the interval(s) on which the profit function is increasing. Upper C (x )equals 0.17 x squared minus 0.00016 x cubed Upper R (x )equals 0.362 x squared minus 0.0002 x cubed

Therefore profit function is increasing on the interval (0,3200)

Step-by-step explanation:

The cost function of the manufacturer C(x) is given as:

The Revenue function is also given as:

Profit=Revenue-Cost

Therefore:

P(x)=R(x)-C(x)

The Profit Function,

To determine the point where the function is increasing, we take the derivative and examine it's critical points.

The derivative of the profit function is:

Set the derivative equal to zero.

x=0 or

x=0 or

x=0 or x=3200

Now let's choose 2000 and 4000 as test points.

Therefore profit function is increasing on the interval (0,3200)
