Finding Asymptotes and Holes of Rational Functions 640 480 joshua

Finding Asymptotes and Holes of Rational Functions

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.

Heats of Dissociation

All molecules are held together by bonds. These bonds come in different lengths, strengths, and numbers, but they all share one thing in common: energy. All bonds store energy which can be utilized in chemical reactions. To break a bond, energy must be put into the molecule, or system, and when a bond is formed,…

A Quick Start Guide to Bohr-Rutherford Diagrams

Bohr-Rutherford diagrams are simple atomic models that show the number of electrons in each shell of an atom. While they are a major simplification of what really happening in an atom, they can be useful to help with visualizing electrons orbiting a nucleus. Drawing Bohr-Rutherford diagrams is super easy using the following steps:   Find…
