**input and output**are terms that relate to functions. Both the

**input and output**of a function are variables, which means that they change. A simple example is y = x

^{2}(which you can also write f(x) = x

^{2}). In such cases, x is the

**input**and y is the

**output**.

Also question is, what is an input output machine?

**Input**-**output** tables are like **machines**: we put numbers into the **machine**, and the **machine** uses an operation (add, subtract, multiply or divide) to give us a result. If the **machine** is using multiplication as a rule, the **output** will be multiples of that rule.

Furthermore, how do you find the input? **Find** the given **input** in the row (or column) of **input** values. Identify the corresponding output value paired with that **input** value. **Find** the given output values in the row (or column) of output values, noting every time that output value appears. Identify the **input** value(s) corresponding to the given output value.

In respect to this, what is the rule in the input output table?

An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number (@$egin{align*}xend{align*}@$-**value**) by 3 to find each output number (@$egin{align*}yend{align*}@$-**value**).

What is an input value?

The first **value** of a relation is an **input value** and the second **value** is the **output value**. A function is a specific type of relation in which each **input value** has one and only one **output value**. An **input** is the independent **value**, and the **output value** is the dependent **value**, as it depends on the **value** of the **input**.
