Learn how to determine the domain from a rational function
👉 Learn how to find the domain of rational functions. Recall that the domain of a function is the set of possible input values (x-values) of the function. For a rational function, the denominator cannot be zero. Thus, to find the domain...

Algebra 16 - Real - Valued Functions of a Real Variable
Although the domain and codomain of functions can consist of any type of objects, the most common functions encountered in Algebra are real-valued functions of a real variable, whose domain and codomain are the set of real numbers, R.

How to define sets and set notation
In this playlist I show you how to understand set theory. I introduce sets as venn diagrams, mapping and as sets of numbers. With sets we look at how to find the union, compliment, and intersection of given sets. We introduce sets with...
