x^3+x^2-40x-84. 2. Using both fundamental Theorem and Descartes` rule of signs‚ prove to the construction foreman that your function matches your graph. Use complete sentences. Answer: Using Descartes’ Rule of Signs can determine the possible numbers of solutions to the equation. By looking at f(x) = x^3+x^2-40x-84‚ you can see that there is one sign change meaning that there is one positive root. Now look at f(-x) version of the previous equation: f(-x)=-x^3+x^2+40x-84‚ there are two sign changes meaning

Linear Programming Concept Paper There are two types of linear programming: 1. Linear Programming- involves no more than 2 variables‚ linear programming problems can be structured to minimize costs as well as maximize profits. Due to the increasing complexity of business organizations‚ the role of the management executive as a decision maker is becoming more and more difficult. Linear programming is a useful technique to solve such problems. The necessary condition is that the data must be

Chapter 2: Linear Functions Chapter one was a window that gave us a peek into the entire course. Our goal was to understand the basic structure of functions and function notation‚ the toolkit functions‚ domain and range‚ how to recognize and understand composition and transformations of functions and how to understand and utilize inverse functions. With these basic components in hand we will further research the specific details and intricacies of each type of function in our toolkit and use
