function
A function is a rule which assigns exactly one output f(x) to every input x.
A Function
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.
The relationship where each input value results in exactly one output value is known as a function. In mathematical terms, a function assigns a unique output to each member of its domain, ensuring that no input corresponds to more than one output. This characteristic distinguishes functions from other types of relations, where an input could potentially map to multiple outputs.
It's a type of function
Function
It assigns exactly one output value for each input 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")(;
That's a proper function, a conformal mapping, etc.
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.
Is called "function".
