**Function notation**is the way a

**function**is

**written**. The f (x)

**notation**is another way of representing the y-value in a

**function**, y = f (x). The y-axis may even be labeled as the f (x) axis, when graphing. Ordered pairs may be

**written**as (x, f (x)), instead of (x, y).

Beside this, why do we use function notation?

**Function notation** can be used to generate points on a graph or find the value of the **function** for a specific value of x. It is a convenient, shorthand way to study what a **function's** values are for different values of the independent variable x.

**Function notation**is the way a

**function**is written. It is meant to be a precise way of giving information about the

**function**without a rather lengthy written explanation. The f (x)

**notation**is another way of representing the y-value in a

**function**, y = f (x).

Beside this, what does f3 mean?

It **means** that you have a function that every time you input a value of x gives you **3** .

Some **Examples** of **Functions** x^{2} (squaring) is a **function**. x^{3}+1 is also a **function**. Sine, Cosine and Tangent are **functions** used in trigonometry. and there are lots more!
