Common Core State Standards
Functions
Linear, Quadratic, and Exponential Models
Interpret expressions for functions in terms of the situation they model
Lessons (6)
Explores derivatives and the idea of infinity using a geometric interpretation of slope.
Teaches distinguishing between possible and impossible graphs of functions as well as causes of graphical impossibility.
Introduces the basic ideas needed for understanding linear functions.
A capstone lesson to allow students to build a working definition of fractal.
Demonstrates the connections between formulas, graphs and words.
Introduces students to the vertical line test for graphs of functions.
Activities (8)
Enter a set of data points, then derive a function to fit those points. Manipulate the function on a coordinate plane using slider bars. Learn how each constant and coefficient affects the resulting graph.
View the graph and the equation of the line tangent to any function at any point on the function.
Determine the fractal dimensions of several line-deformation fractals. Input the scale factor and number of similar copies, and the dimension will be calculated. Fractal Dimensions is one of the Interactivate assessment explorers.
A more advanced version of Slope Slider, this activity allows the manipulation of the constants and coefficients in any function thereby encouraging the user to explore the effects on the graph of the function by changing those numbers.
Students can create graphs of functions entered as algebraic expressions -- similar to a graphing calculator.
Create graphs of functions and sets of ordered pairs on the same coordinate plane. This is like a graphing calculator with advanced viewing options.
Review the properties of functions by looking at ten different curves and deciding whether or not they meet the criteria for a graph of a function. This activity simply displays the curves - it does not quiz the user.
Learn about the vertical line test for functions by trying to connect points in the plane to build a function. When you have connected all of the points, you will be told if your graph is a valid graph of a function. Vertical Line Test is one of the Interactivate assessment explorers.
