1. Topic Of Lesson Plan

Writing and Graphing Functions 


2. Lesson Content

Standards:
16.0 Students understand the concepts of a relation and a function,
determine whether a given relation defines a functions, and a given
pertinent information about given relations and functions
17.0 Students determine the domain of independent variables and the
range of dependent variables defined by a graph, a set of ordered
pairs, or a symbolic expression
Vocabulary Terms
Dependent Variable
Independent Variable
Function Notation 


3. Goals And Expectations

1.Write an equation in function notation and evaluate a function
for given input values
2.Graph functions and determine whether an equation represents a function
3. 


4. Objectives

1. Find relationship between x and y values
2. graph equations
3. Determine whether an equation is a function 


5. Materials and Aids

Doc cam, paper, colored paper, graph paper, colored pencils, rulers,
graphing calculators(maybe??) 


6. Methods Used and Procedures

A. Introduction
1.Determine relationships between x and y values
2.Graphing Functions 


B. Development
1.Independent/Dependent Variables:
Independent when I don't eat > Dependent I get cranky
Independent> if I don't work > Dependent then I don't get paid
REMINDER* F(X) does not mean f times x, notation is interchangeable
with y
2. Function any vertical line will intersect the graph of a function
no more than once.
3. Explain different functions result in a certain type of graph 


C. Practice
1.Students and Teacher will practice graphing functions on a small
sheet of graphing paper
2. Students will work with partners graphing functions 


D. Independent Practice
1.Working with partners students will pick negative and positive
values and graph functions depicting an array of different graphs
2.homework 


E. Accommodations For Students

F. Checking for understanding

G. Closure
1. Functions are determined by the relationship between the x and
y values
2. Functions depict different graphs 


7. Evaluation
