Shows how to ofirst find the coordinates of the vertex, then choose other inputs to find two more points on each side of the vertex, plott them and draw the graph.


Shows how to shoose appropriatate input values to find five points, then plot them and draw the graph.


This video explains the situation we are trying to minimize or maximize and the role of the input and output variables. Then the process of finding the location and value of the requested amount is…


This video describes why the method for finding the intercepts works, then demonstrates finding the intercepts for an example equation and graphing its line.


Another demo on how to use the yintercept to start a graph of a linear equation and then use the slope to find other points on the graph. It finishes with showing the line representing all of the…


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…


Shows how to determine the boderline separating the side of the xy graph that has true solutions from the side that does not. It is then shown how to decide whether that line should be dotted or…


Demonstrates how to make t his graph per instructions, and also shows how to deal with a fractional leading coefficient.


Just showiing how to locate and write down the xintercepts and yintecepts when looking at a graph


Shows how to write the domain and range of a graph of an unbroken function with a starting point and an ending point.


Simply demonstrates how to interpret function notation to understand what is being asked. In the example, the input is shown using function notatiion and the question asks for the function value or…


Demonstrates how to solve a standard form equation for y to get the slopeintercept form y = mx + b


A second video describing how to find x and yintercepts.


Shows how to substitute zero for y to find the xintercept and zero for x to find the yintercept.


Finding the points where a particular graph crosses each axis on the xy coordinate plane.
