A Function
It is a functional relationship which has an input and an output. Addition, subtraction, multiplication, division, reciprocals, exponentials, logarithms are all examples.
It is a injective relationship. However, it need not be surjective and so will not be bijective. It will, therefore, not define an invertible function.
The relationship between the input and output values can be determined by a mathematical function or rule. In this case, when the input is 1 and the output is 8, the rule could be represented as f(x) = 8x, where f(x) is the function and x is the input value. This means that the output is obtained by multiplying the input value (1) by 8.
There need not be any relationship.

A one-to-one or injective function.
The relationship is called a surjection or a surjective function.

Output from what? Of a mathematical function? Of a computer procedure? Of a machine? Of a river? And what type of output? Please clarify your question.
A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output.
The relationship between the input and output values can be determined by a mathematical function or rule. In this case, when the input is 1 and the output is 8, the rule could be represented as f(x) = 8x, where f(x) is the function and x is the input value. This means that the output is obtained by multiplying the input value (1) by 8.
For a relationship to be considered a function, each input value must correspond to exactly one output value. This means that each input cannot have multiple outputs.
