It assigns exactly one output value for each input value.
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.
Function
The change in the input value is equalto the change in the output value.
a function is just a rule which takes certain values as input values and asign to each input value exactly one output value (you must be wondering what the "F" is in input or an output value? Well, they are just a fancy name for "variables")(;
A function is a rule which assigns exactly one output f(x) to every input x.
It assigns exactly one output value for each input value.
It is a bijective function.

I found two answers for this question. A function is a rule that assigns to each value of one variable (called the independent variable) exactly one value of another variable (called the dependent variable.) A function is a rule that assigns to each input value a unique output value.
Answer - True, answer on apex.
Function
A one-to-one or injective function.
No, not every relation is a function. In order for a relation to be a function, each input value must map to exactly one output value. If any input value maps to multiple output values, the relation is not a function.
Anything you like - it depends on the function that relates the output to the input.
The change in the input value is equalto the change in the output value.
