A relation is a function if there is exactly one output for each input ⇒ b
Step-by-step explanation:
Let us revise the meaning of relation and function
- A relation is a set of inputs and outputs that are related in some way
- When each input in a relation has exactly one output, the relation is said to be a function
- A function is a relation with one output for each input
Examples:
{(1 , 2) , (-2 , 3) , (1 , 5) , (2 , 4)}
∵ x is the input
∵ y is the output
∵ The input 1 has two output 2 and 5
∴ The set above is a relation
{(1 , 2) , (-2 , 3) , (-1 , 5) , (2 , 4)}
∵ x is the input
∵ y is the output
∵ Each input has only one output
∴ The set above is a function
A relation is a function if there is exactly one output for each input
