The ordered pair (4 , 1) must removing from the table to make the relation a function ⇒ last answer

Step-by-step explanation:

Let us revise the relation and the 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, then the relation is said to be a function
  • {(1 , 2) , (-3 , 4) , (1 , -1)} is a relation because the input 1 has two outputs 2 and -1 , {(2 , -4) , (-3 , 5) , (4 , -1)} is a function because every input has only one output

The table is:

→  x    :    y

→  1     :    7

→  4     :    7

→  2     :    2

→  4     :    1

→  3     :    9

x is the input and y is the out put

The ordered pairs are (1 , 7) , (4 , 7) , (2 , 2) , (4 , 1) , (3 , 9)

∵ x = 1 has y = 7

∵ x = 4 has y = 7

∵ x = 2 has y = 2

∵ x = 4 has y = 1

∵ x = 3 has y = 9

- The input 4 has two outputs 7 and 1

∴ We must remove (4 , 7) or (4 , 1) to make the relation a function

∵ The choices has (4 , 1)

∴ We must removed the ordered pair (4 , 1) from the table

The ordered pair (4 , 1) must removing from the table to make the relation a function
