Hi, I'm Karessa Pentagon, currently attending Oakland High School. I have attended Franklin Elementary School, Westlake Middle school, and now in high school. I volunteered at the Oakland main library this summer but I haven't had any official paying job. When I grow up, I wish to be a successful nurse or a doctor, but if that plan fails I also want to be a business woman, possibly running my own company or store. In my free time, I enjoy reading and writing, going online, and listen to music, I just want to have fun.

### Example

By Wendy Huynh

This assignment was related to Chapter 2 of our Trig. textbook-Functions and Relations. We have already learned how to plot number-line graphs of equations with one variable. Now, things get more challenging......we are going to work with equations containing TWO variables!!!

A graph is a function if for every x value, there is exactly one unique value of y. A relation is just the opposite. It has two y-values for every x-value. The independent variable is x, and the dependent variable is y. The domain of a function is the set of values of the independent variable, and the range is the set of values of the dependent variable. In this chapter, I learned to sketch a reasonable graph when given a real-world situation in which one variable depends on the value of the other.

We worked in pairs, and me and my partner Ivan decided to use computers as our real-world example. Every time we hit a single letter on the keyboard, that same single letter appears on the computer screen. We then repeat this experiment multiple times and find that it is true for each trial. This situation is known as a FUNCTION. But suppose our computer gets a little "weird" and when we hit the same letter more than once, a different letter appears on the screen. In this case, there are two possible outcomes for each letter that we type. Therefore, this would be called a RELATION. Our detailed work is shown below. Enjoy!

### How to Do About Me

Title: About "First Name Last Name"

Background: Education - List the schools you have attended

Work and Volunteer -List any paid or volunteer jobs you've had.

What I want to be: What do you want to be when you grow up?

Interests: Tell us you favorite things to do or hobbies

Photo: Include a picture of yourself or one that represents you.

### Guidelines

Here are a few simple guidelines:

1. Make sure that your real name and math last name in your profile.

2. Always make every picture as large as possible.

2. Don't ever create a new label.
3. Don't ever use the "How To" Labels
4. For each entry, chose the project name label.

### Previous Years Blogs

The objective of student blogs is to create an interactive online portfolio of work in math class each year. Each time we complete a project students add an entry to their web page or blog. Students build portfolios that demonstrate their mastery of mathematics.
