What is the range of the function in this table

Option D is correct

(1,2,4)

Step-by-step explanation:

Given is a table as

xy

21

34

44

52

Here we are asked to find the range

Range is the values of y which have preimages as x

Here we find that the items y=1,4,2 have preimages in x

Hence range = (1,4,4,2)

Write in order and write only once the repeated values to get range as

Range = {1,2,4}

Option D is right
