Trying to figure out if the values in a replacement set are part of the solution set to an inequality? Learn how to find the answer to that question with this tutorial!
You can't do algebra without working with variables, but variables can be confusing. If you've ever wondered what variables are, then this tutorial is for you!
This tutorial will help you understand what a set is, and the different kinds of sets that you may see when you're working on algebra problems :)
Inequalities come up all the time when you're working algebra problems. In this tutorial you'll learn what an inequality is, and you'll see all the common inequality symbols that you're likely to see :)
Got a set of ordered pairs? Then you have a relation! This tutorial takes a look at relations!
To find the solution set of an equation with a given domain, you first need to plug each value in the domain into the equation to get the respective range values. Create ordered pairs from these values and write them as a set. That set is your answer! Learn it all in this tutorial!
Even graphs need to worry about tests! Using the vertical line test, you can figure out if a graph is a function or not. Watch this tutorial and learn about the vertical line test. Then, put your graphs to the test!
