Hi
We are starting with functions today:
1. Read this page and send me an email with the most important things you see there. You should find what a function is, what rules it has and what domain means, at least.
2. Open this Geogebra applets with a simple example of a function.
Now, play with them and try to answer these questions:
a) What does f(3) mean? How much is it? How can you calculate that?
b) Are there more than one value of a with the same value of f(a)? Is that possible in a function?
Send me the answers.
3. Now we are going to create something similar. Pay attention and send me the file.
4. Read pages 40 and 41 of this book . They show you how to calculate the domain of a function.
5. With this information, solve these exercises:
6. More exercises.
You can find the same exercises with solutions in this link.
