Description:

In this activity, students input a function where the constants, coefficients, and exponents can be adjusted by slider bars. Students can also input data points to be graphed in the same window. This activity allows students to explore graphs of functions and how adjusting the numbers in the function affect the graph. Students can also practice adjusting the parameters of an equation in order to find a function representation of their data. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.

CCSS.Math.Content.8.SP.A.2: Common Core State Standards for Mathematics

Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.

CCSS.Math.Content.HSF-IF.B.4: Common Core State Standards for Mathematics

For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship.?

CCSS.Math.Content.HSF-IF.C.7a: Common Core State Standards for Mathematics

Graph linear and quadratic functions and show intercepts, maxima, and minima.
