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
It assigns exactly one output value for each input value.
A Function
There need not be any relationship.
A function.
Relation
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.
function
It is a bijective function.
It is a mapping which assigns one or more outputs to each set of one or more inputs. A relationship need not be a function.
A Function
The relationship is called a surjection or a surjective function.
This is true. Furthermore, functions can be broken down into one-to-one (each input provides a different output), and onto (all of Y is used when f(x) = y).
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.
Answer - True, answer on apex.
There need not be any relationship.
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.
