An input value is the value that you start with. If it helps, you can think of an input value as being a value you type in. So, for instance, if you type 8 * 2 into your calculator, then that's the input.
This is contrasted with output, which is the value returned to you by the computer program. In our example, the output would be 16.

What is the output value if the input value is 4?
Without knowing the specific function or equation being used, it is impossible to determine the output value if the input value is 4. In mathematics, the output value is dependent on the specific function or equation being evaluated. To find the output value when the input value is 4, you would need to know the function or equation being used and then substitute 4 in place of the input variable to calculate the output value.
What does function rule mean in math?
The rule of a function in math is what relates the input value to the output value. For example, if f(x) = x2, the "function rule" is to square the input value to get the output value.
What is a dependent quantity?
the output of a function; a variable whose value depends on the value of the input.
What is the term for a relation in which each input value corresponds to exactly one output value?
A one-to-one or injective function.
What does the x in f x mean?
It is the input value to the function called "f(x)" If f(x)= x + 1, an input value of 2 ( x equals 2) would give us 2 + 1, or 3.
