precal - types of functions
posted by Anonymous .
Spider Industries is a U.S.-based company that test-marketed 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?
hah well actually, that was my first thought, but not one of the choices given.
no need for smart comments thanks ;)
