Logarithms are often used in science to model things like sound (decibels), earthquake strength (Richter scale), and pH (for the strength of acids or bases).  Logarithmic functions have some...

Functions are useful in many areas of mathematics, and odd functions have an interesting property that is worth investigation. So, what is an odd function?  Algebraically, an odd function...

We know that a function cannot have different y values for a single x value.  However, that still leaves the question of whether different x values can lead to the same y value as output. So,...

Functions are useful throughout mathematics, and even functions have certain special properties that make them easier to work with. So, what is an even function?  Algebraically, an even...

Slope is an important concept when it comes to working with lines and their graphs.  Knowing what the sign of the slope means will make it much easier to understand linear functions. So, what...

Quadratic functions are often used in mathematics, especially when solving quadratic equations by graphing.  If you are wondering exactly what a quadratic definition is, I have a simple...
