It is a bijective function.
A function is a rule which assigns exactly one output f(x) to every input x.
function
A relation is a function if every input has a distinct output.
A one-to-one function, a.k.a. an injective function.
No. If an input in a function had more than one output, that would be a mapping, but not a function.
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.
Answer - True, answer on apex.
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).
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.
It's a type of function
That's a proper function, a conformal mapping, etc.
Is called "function".
A one-to-one or injective function.
function
A relation is a mapping or pairing of input values with output values.
An example of a relation that is not a function is the relation defined by the set of points {(1, 2), (1, 3), (2, 4), (3, 5)}. In this relation, the input value 1 corresponds to two different output values (2 and 3), violating the definition of a function, which states that each input must have exactly one output. Therefore, since one input maps to multiple outputs, this relation is not a function.
