Solving Quadratic Equations

Solving Quadratic Equations 485 254 Jeff
The quadratic equation is one of the most important topics in math, but sometimes it could look a bit complicated. We explore some of the simplest methods to solve quadratic equations and offer some examples of each. read more

Finding Asymptotes and Holes of Rational Functions

Finding Asymptotes and Holes of Rational Functions 640 480 joshua
Here we will be looking at some defining features of rational functions: asymptotes and holes. We will begin by defining rational functions,. We will then proceed to uncover how to identify different types of asymptotes and how to distinguish them from holes. In each case, we will use example functions to visualize the effects and representations of these features. read more
