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


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


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 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 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…


For an equation with f(x) equal to a rational expression, this shows how to write the substitution and simplification when putting in a particular value for x.


Demonstates how to interpret a graph of a system of functions so that common questions that someone might have can be answered.


Shows how thits form is simply the same as y = mx + b, and then writes the slope and yintercpt down. It ends with using these to graph the line of points that satisfy this function.


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


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…


Describes a situation that can be written as a function of the number of weeks a certain amount it saved and the resulting functional value is the amount still needed to be saved to buy something. …


Shows how to input an expression in place of the orignial variable input, and then simplify.


Speaks to the meaning of f(x), i.e. function notation. Then demnstrates how to get the value of two different functons given the input value.


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…
