__Math Tutoring on Determining Function Values__

Now that we know a **function** is a special relation in which each input has exactly one output we often use special notation to communicate that a relation is a **function**. The notation is called **function notation**, for example, **y = f(x)**. So **f(x)** is **function notation** where **f(x)** is the output resulting from applying the **function rule f** to the input **x**. So when using **function notation we** need to remember that **x** is the input and **f(x) **is the output and therefore **f(x) = y**. When we first see this notation though it is easy to think that this means **f** times **x**, but it does not. Its special notation called **function notation**.
