## What does function notation mean?

Function notation is a way to write functions that is easy to read and understand. Functions have dependent and independent variables, and when we use function notation the independent variable is commonly x, and the dependent variable is F(x).

## How do you graph a function on a TI-84?

On the TI-83 and TI-84, this is done by going to the function screen by pressing the “Y=” button and entering the function into one of the lines. After the function has been entered, press the “GRAPH” button, and the calculator will draw the graph for you.

**What is function notation and how does it work?**

### What is a function and function notation?

Function Notation. The notation y=f(x) defines a function named f. This is read as “y is a function of x.” The letter x represents the input value, or independent variable. The letter y, or f(x), represents the output value, or dependent variable. Example 1.1.

### How do you calculate the graph of a function?

Write down the relation. A relation is a set of ordered pairs with of x and y coordinates.

**How do you tell if a graph represents a function?**

Constant Function. A function f: R → R defined by f ( x) = c,∀ x ∈ R is called a constant function.

#### How to determine whether the graph is a function?

Stick a “y” in for the “f (x)” guy:

#### What are the functions of a graph?

Evaluating functions.
