|
Presents a compound inequality where both sides have to be solved for the variable first, and then shows how to graph the simplified results
|
|
A demonstration of how to deal with interpreting the union and intersection of two inequalities. For a more extensive and exhaustive demo, please view the videos entitled "Understanding…

This presents how to graph two inequalities that are connected by either the word "or" or the word "and"
|
|
A somewhat fancierversion of seveal solving equation versions that should help solidify the process in your mind.

|
This shows how to find the vertex of a parabola and then calculate the matching points one unit and two units to the left and right of hte axis of symmetry
|
|
This has two examples so that you can learn to watch out for what looks like a solution but is not because it creates division by zero if you check the answer in the original equation. The other…

|
Demonstrates how to start at the y-initercept point on the grid and then use the slope to find other points on the line graph.
