Please Help i give medals
You are having a meeting with the CEO of a technology company. You have interpreted the number of laptops produced versus profit as the function P(x) = x4 3x3 8x2 + 12x + 16. Describe to the CEO what the graph looks like. Use complete sentences, and focus on the end behaviors of the graph and where the company will break even (where P(x) = 0).

Best ResponseYou've already chosen the best response.2Ur prob does not ask "how to" get it but it asks for a description of what the graph looks like. So it is perfectly fine to use wolframalpha to plot the graph and write up the description yourself.

Best ResponseYou've already chosen the best response.2Welcome! For self knowledge, it is a 4th degree polynominal so it can be of many different shapes. In general, u would have to set up a spreadsheet n calculate the values of P(x) over a range of x. good luck :)

Best ResponseYou've already chosen the best response.0See the link for info on polynomial end behavior. http://www.purplemath.com/modules/polyends.htm Basically your polynomial is of even degree (4) and your leading coefficient is positive (1) so the function increases toward infinity as x increases toward infinity. It's a reasonable assumption that you're only interested in the part of the graph where x≥0 since x is units sold, so for the break even part, find the positive zeros of P(x). You can actually factor your equation so the zeros are easy to pick out
