Function notation, like $f(x)$, can be tricky for students.

Reading Functions:

It can be hard to figure out what $f(x)$ means.

Basically, $f(x)$ tells you what you get when you put in a number, called input $x$.

Writing Functions:

Making your own function notation isn’t always easy.

You need to understand things like variables and how to use them in math.

But don’t worry if you find these ideas tough!

You can get better with practice.

Using pictures or charts can help you, too.

And if you're ever stuck, asking your teacher or friends can clear things up!
