Refresher

 

This is a play button that opens Inequality.

Use the Inequality definition and applet to review the inequality symbols, the graphs of inequalities in one variable, and solving inequalities.

 

 

 

 


 

This is a play button that opens Graphing y = mx + b.

Use Graphing y = mx + b to review how to graph linear functions in the form y = mx + b. Select Linear Functions, and then select Graphing Equations in the Form y = mx + b on Graph Paper.


 

Refresh your skills in graphing a quadratic function.

  • Return to Module 3: Lesson 3 to review how to convert a quadratic function in standard form to vertex form by completing the square.

  • Use Quadratic Function (Vertex Form) to review the graphs of quadratic functions in the vertex form.

     
    This is a play button that opens Quadratic Function (Vertex Form).
