Spider Industries is a U.S.based company that testmarketed an electronic cobweb destroyer in Japan. The company's revenue, R, is a function of the number of destroyers sold, x, using the following formula R = 160x 0.2x^2.
What type of function did Spider Industries use to describe its revenue as a function of sales?

You are planning to take Calculus and you do not recognize R = 160x  1.2x^2 as a quadratic function?
Mmmmh!
