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
