Virtual Nerd: How Do You Graph the Union of Two Inequalities?

The intersection of two inequalities is what they have in common. This tutorial shows you how to graph two inequalities on the same number line and then find the intersection. [2:40]

Two given inequalities and you need to find the union. What is the union? Well, it just means that you need to show the graphs of the given inequalities on the same number line. Keep in mind, less than, greater than, and equal to, and...

Intersection. Isn't that where paths cross? And so it is in math also. Observe the teacher as she draws a number line and plots two inequalities on it. She then explains how to get the intersection of these two lines. Then she draws...

This tutorial will demonstrate how to graph an inequality and an infinite set on a number line. Closed and open circles are discussed using specific examples. [3:37]

To graph a function, you first need a table of values to fit your equation. This video will demonstrate how to make a table and then plot those values to make a graph. [3:23]

This tutorial demonstrates how to solve a multi-step equation for a variable. A step by step process is given with examples. [3:45]

Probability is the likelihood that a given event will take place. So how do you determine the probability of a simple event? Watch this example using marbles for an explanation. [4:36]

Learn how to solve an inequality using the subtraction property. This video will demonstrate the process using a number line. [3:49]

What happens when you have too much data to fit neatly on a bar graph? Watch this video to see an example of a set of data that is too big to fit all the intervals and how we interpret this type of graph. [4:29]
