The price of an item is given by p=2xsquared - 100. Find the polymonial that represents the revenue generated from the sale of x items.

Multiply the price term, 2x^2 - 100, by the number of sales, x. That should be the revenue from selling x units.

The p(x) relationship you have been given does not make sense to me. It would imply the price becomes negative if none are sold. It also implies that the number of unit sales, x, increases with price.
