What is the range of the function in this table

Answer:
Option D is correct
(1,2,4)
Step-by-step explanation:
Given is a table as
x y
2 1
3 4
4 4
5 2
------------------------
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
Answer:
Choice D is the correct answer.
Step-by-step explanation:
We have given a table of values of x and y.
We have to find the range of the function.
Range is defined as the set of all output values of function.
The values of y are called outputs and the values of x are called input.
Hence, the values of y are 1,4,4 and 2.
Range = {1,2,4} which is the answer.
