What's the difference between a relation and a function?
Understand the Problem
The question is asking for the distinctions between a relation and a function in mathematics, focusing on their definitions and properties.
Answer
In a relation, one input can have multiple outputs; in a function, each input has exactly one output.
The primary difference between a relation and a function is that in a relation, a single input can have multiple outputs, while in a function each input is associated with one and only one output.
Answer for screen readers
The primary difference between a relation and a function is that in a relation, a single input can have multiple outputs, while in a function each input is associated with one and only one output.
More Information
All functions are relations, but not all relations are functions. In mathematics, functions are a significant concept due to their predictability and unambiguous mapping from inputs to outputs.
Tips
A common mistake is to assume every relation is a function. Always check if each input has a unique output to determine if it is a function.
