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 shows the method of using the pointslope form to write the equation, then solving that form for y to get y = mx + b.


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 explains how to use the slope and yintercept to determine points on the line graph of a linear equation in two variables and then draws the straight line graph.


Just a short demo of how read the location of an (x, y) point on a Cartesian coordinate graph


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 enter a value into a function to get a result for something like depreciation of value over time for a purchased item.


This shows how to decide whether you are seeking a maximum or minimum value for a quadratic function and then how to find the vertex of i ts parabola to deternine the xvalue that locates the min…


This demonstrates how to find these values for a quadratic equation of the form y = ax^2 + bx + c.


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


Application of the equation relating the three sides of a right triangle:: a^2 + b^2 = c^2 where a and b are the shorter sides that make the rigiht angle and c is the lenght of the longest side.


A twostep process involving first removing the greatest common factor from both terms, then factoring the resulting difference of squares.


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…
