Question

What is the range of the function in this table

Answer 1

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.

Answer 2

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
