## Description

Chapter 1 Project

Objective:

The world is full of different shapes. This project requires you to find examples of the 12 basic shape functions we just finished studying and to take a picture of each one. Signs and logos are a great place to start.

Directions:

After gathering your 12 pictures, label each one with the name and the equation of the function. Capture a screen shot of the function from your graphing calculator and include a sentence or two about the picture. What did you take a picture of and where did you take it? Superimpose the shape of the function over the picture (see examples). ALL PICTURES SHOULD BE TAKEN OUTSIDE OF SCHOOL

Here’s a list of the 12 basic shapes:

Linear function: f(x) = x Absolute Value function: f(x) = x

Reciprocal function: f(x) = Squaring function: f(x) = x2 x1

Cubing Function: f(x) = x3 Square Root function: f(x) = x

Sine Function: f(x) = sin x Cosine function: f(x) = cos x

Log function: f(x) = ln x Exponential function: f(x) = ex

Logistic function: f(x) = Greatest Integer function: f(x) = [x] x e 1 1

You may work with one other person or you may work alone.

When you turn it in, staple the following together:

1) A cover page (include subject, name(s), date)

2) Introduction: Describe the project. Talk about what you learned doing this project.

3) 12 pictures (no more than 6 per page) with a sentence or two about the picture

4) The basic shape should be superimposed over each picture

You are to turn in both a hard copy and an electronic copy of the project. Extra credit will be given to pictures that are original and clever. Samples and a scoring rubric are on the back.

Due date: October 6th
