Solve using two step method inequality
👉 Learn how to solve two-step linear inequalities and graph their solution. When solving two step inequalities we will use inverse operations, reverse order of operations and the properties of equality to solve. We will then graph our...

How do you find the domain and range of a function
Learn how to determine the domain and range of a function given the graph of the function. Since the domain of a function is the set of all x-values we will want to identify how far left the graph goes as well as how far right to...

Graphing an inequality when you have to switch the sign
👉 Learn how to graph linear inequalities with one variable. Linear inequalities are graphed the same way as linear equations, the only difference being that one side of the line that satisfies the inequality is shaded. Also broken line...

Solving a multi-step inequality and then graphing
👉 Learn how to solve multi-step linear inequalities having parenthesis. An inequality is a statement in which one value is not equal to the other value. An inequality is linear when the highest exponent in its variable(s) is 1. (i.e....

Solving Inequalities Using Multiplication or Division
In this video lesson we will apply the Properties of Inequality using Multiplication and Division. We will discover that when you multiply or divide both sides of an inequality by the same POSITIVE value the result is an equivalent...

Using multi steps to to solve an graph one variable inequalities
👉 Learn how to solve multi-step linear inequalities having parenthesis. An inequality is a statement in which one value is not equal to the other value. An inequality is linear when the highest exponent in its variable(s) is 1. (i.e....

Graphing a rational function with discontinuity
👉 Learn how to graph a rational function. To graph a rational function, we first find the vertical and horizontal or slant asymptotes and the x and y-intercepts. After finding the asymptotes and the intercepts, we graph the values and...

Solving absolute value inequalities when there are infinite many solutions
👉 Learn how to solve multi-step absolute value inequalities. The absolute value of a number is the positive value of the number. For instance, the absolute value of 2 is 2 and the absolute value of -2 is also 2. To solve an absolute...
