yes
function
The rule is what actions (operations) the function performs. The only requirement is that for each imput there is an output and that the same input always results in the same output. (Different inputs can have the same output).
It's a type of function
Each input has only one output. The same input will always produce the same output. The function can be represented by an equation or a graph.
function
One output for each input
A function has an input and an ouput. Each input can only have one output. Examples of functions: x = y y = x2 y = cos(x) where y is the output and x is the input.
A Function
A mapping. It need not be a function.
An overall function is a function where each input value is uniquely associated with one output value. This means that each input has one clear, defined output. Overall functions maintain clarity and consistency in their mapping between inputs and outputs.
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.
