Basic Functions
Students need the best teacher, so you need examples,
because examples are the best teacher. All the
examples here are fully worked and explained, and help
run your math easier and fast enough.
And this book covers functions, and explains what a
function is about, how it gets made, how it behaves,
and what we can do with it or how to use it.
What then is it for?
A function is a math concept, and is a math tool. Using
it, we can see how things are related to each other. And
the things are two data sets. One data set depends on
the other data set.
Thus, this book helps get the idea of a function, the
concept, and you will get to see how to work with it,
because the book explains many basic functions, how
they get made, and how they work, along with their
nature so that you can develop your own idea, to solve
problems, of course.
This book is in fact, for your algebra, and helps grow it
through examples. Some examples may look too easy
or too hard. It all depends on your skill of algebra.
Whatever your skill may be though, you can grow yours
following the steps in each example. Each is detailed so
that you can learn how to handle math expressions fast,
and increase your caliber in algebra quickly, as well as
properly.
You should not just follow steps in the books or
example sets. After your understanding, you should
solve all examples by yourself without looking at the
steps. If only you do it yourself, it’s all yours.
And doing it, put your steps in your writing without
looking at the steps in the solution pages. Also, use a
pen, not a pencil. Making an error, just cross that out
with a single strike only, put the correction next to it,
and move on so that you can check what you have
done. Using erasers, you cannot see what you have
done. We learn a lot from mistakes. And that’s not it.
You can find and get a lot of examples, practice
sets, on this website: www.runmath.com. Thus, you
may want to go to the web page for the book samples
and practice examples, and get them downloaded
and do them all.
The book is available at Amazon. (The key words: Basic
Functions, Seong Kim) You can read the sample or get
it downloaded clicking

pdf reader, your
reading the sample is much easier.
May your math run very well.
