Modeling- Linear Functions, Quadratic Functions, Exponential Functions PT 1
By Textbook Tactics
Determining if data fits a Linear, Quadratic, or Exponential Model by graphing the data or finding patterns in the data.
Modeling with one-variable equations and inequalities
By Khan Academy
Sal models a context that concerns a candy vending machine. The model turns out to be a quadratic inequality.
Linear Quadratic and Exponential Models
By Khan Academy
Watch this video to learn how to identify linear and exponential functions from input output tables. Linear functions grow by equal differences over equal intervals so as x increases or decreases at a constant interval you add or subtract a constant for each corresponding y interval. Exponential functions grow by equal factors over equal intervals so as x increases or decreases at a constant interval you multiply or divide a constant for each corresponding y interval.

Graphing Quadratic Equations
By Marc Whitaker
Instructor uses a white board to model graphing quadratic equations. Examples show using quadratic equations in standard form to determine the line of symmetry, create a table of values, and graph the quadratic equation by using these values.
Quadratic Model: Enclosing a field with a fence
By SuperMathPrincess
How to create a quadratic function that represents the area of a rectangular field as a function of the width of the field, given a specific amount of fencing to enclose the field. Also includes how to find the maximum area and the dimensions of the field needed to obtain that maximum area, both by hand and by using a TI-83 plus graphing calculator.
Compare the growth rates of exponentials and polynomials
By Khan Academy
Sal discusses two functions that model the shipment rate of cars. One function is quadratic and the other is exponential. Which one will eventually exceed the other?
How to Find and Graph the Inverse of a Function | Algebra 2 Math Video
By MrPilarski
http:/www.mrpilarski.wordpress.com In this video lesson, Mr. Pi models how to graph a quadratic function and its inverse. The process starts with graphing a parabola in the form $latex y=a^2+c$. The vertex is given by (0,c). After graphing the parabola with four additional points, Mr. Pi creates the inverses graph by moving the points about y = x line. Finally, Mr. Pi finds the inverse of the original function.
