Interval notation is a method used to write the domain and range of a function. In interval notation, there are five basic symbols to be familiar with: open parentheses (), closed parentheses [], infinity (imagine an 8 s... More »

Function notation is a method of writing algebraic variables as functions of other variables. Most often, functions are portrayed as a set of x/y coordinates, with the vertical y-axis serving as a function of x. For exam... More »

To graph a logarithmic function, the domain of the function is determined, which is a set of all allowable x values. The domain is used to calculate a range of y values. The vertical asymptote gives the value near which ... More »

The domain and range of a function designate the values at which the function exists. In a composite function, one function is being applied to another. You must determine values at which the first function does not exis... More »

In mathematics, a function's domain is all the possible inputs that the function can accept without breaking and the range is all the possible outputs. A real life example of this is using a simple calculator to add two ... More »

A relation is a set of numbers that have a relationship through the use of a domain and a range, while a function is a relation that has a specific set of numbers that causes there to be only be one range of numbers for ... More »

Interval notation is used to describe what numbers are included or excluded in a set. When an arbitrary value x is greater than three but less than five, then in interval notation the set of values for x would be written... More »
