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

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
