Fun With Functions Teacher Notes

Topic: Functions and Function Notation

NCTM Standard:

• Represent, analyze, and generalize a variety of patterns with tables, graphs,

words, and, when possible, symbolic rules.

• Relate and compare different forms of representation for a relationship.

• Identify functions as linear or nonlinear and contrast their properties from

tables, graphs, or equations.

Objective

The student will be able to use the Casio fx-9750GII to input data relating to

functions as well as to evaluate functions using function notation.

Getting Started

Being able to understand functions in various forms empowers students to

see patterns in relationships and make connections with functions to their

everyday lives. Begin this activity by looking at various tables and gain an

understanding of how that data relates to its graph on a coordinate plane.

Students should be able to examine a table and/or a graph and be able to

determine any specific trends or characteristics about that data set.

Prior to using this activity:

• Students should be able to graph points on a coordinate plane.

• Students should be able to read and interpret data presented in a table

and graph.

• Students should be familiar with all key strokes involved in entering data

into a table and entering a function into the graph editor window.

• Students should understand the formula for a linear function.

• Students should be able to correctly identify the independent (x) and

dependent (y) variables.

Ways students can provide evidence of learning:

• When given a function, students can state and explain whether that

function is increasing or decreasing.

• When given a function, students can evaluate it for a specific value of x or

Common calculator or content errors students might make:

• Students may incorrectly set the viewing window when showcasing a

function.

• Students may enter data into a table incorrectly by switching the x- and y-

coordinates.
