Shows how to find outputs for several inputs reslulting in a set of points (x, y)
|
|
|
Just a short demo of how read the location of an (x, y) point on a Cartesian coordinate graph
|
|
|
Presents a compound inequality where both sides have to be solved for the variable first, and then shows how to graph the simplified results
|

|
Shows how to interpret and graph on a number line a set written in set builder notation, then goes on to transfer the line graph to interval notation.
|

|
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 gives a graph of a parabola which is the graph of a quadratic equation or function. The demonstration first includes classifying it as a parabola that is opening downward or upward. Then it…
