Shows how to substitite the given value for the output variable, then rearranges the resulting equation in standard form. Values for a, b, and c are identified and then entered into the quadratic…


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 talks about why we need two equations to solve for two unknown values, and then demonstrates how to add two equations together to eliminate one varaible and solve for the other one, then find…


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.


Shows how to find outputs for several inputs reslulting in a set of points (x, y)


A quick demo about plugging in given values for variables and calculating a number result.


Shows how to plug in the given xvalues and get values for f(x) = b^x


Shows how to find out what values are not defined for a rational function. This ability will be needed when solving rational equations because you may come up with a value that is not valid when…


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


Describes how to find output values for a function given a list of iinput values and a table to complete a set of ordered pair values. Also mentions what function notation means and how to work with…


This demonstrates why and how to use vertical lines to test whether a graph of any relation is a function or not.


Presents the use of the slope formulat we use to calculate the slopes of these special lines.
