To calculate: To determine whether the relation is a function

Answer to Problem 7E
Relation is not a function
Explanation of Solution
Given: Relation is defined as
Input, x | 16 | 1 | 0 | 1 | 16 |
Output, y | -2 | -1 | 0 | 1 | 2 |
Formula Used:
Any set of ordered pairs is a function when none of the ordered pair in set have same first coordinate with different second coordinate
Calculation:
Relation is given as follows:
Input, x | 16 | 1 | 0 | 1 | 16 |
Output, y | -2 | -1 | 0 | 1 | 2 |
Set of ordered pairs are defined as:
(16,−2),(1,−1),(0,0),(1,1),(16,2)
Now consider the ordered pairs (16,−2),(16,2)
Here, first coordinate is 16 , while second coordinates are −2 and 2
Also, consider the ordered pairs (1,−1),(1,1)
Here, first coordinate is 1 , while second coordinates are −1 and 1
There existsfour ordered pairs that have same first coordinate with different second coordinate.
Thus, the relation is not a function
Conclusion:
Hence, relation is not a function

Students in an online course are each randomly assigned to receive either standard practice exercises or adaptivepractice exercises. For the adaptive practice exercises, the next question asked is determined by whether the studentgot the previous question correct. The teacher of the course wants to determine whether there is a differencebetween the two practice exercise types by comparing the proportion of students who pass the course from eachgroup. The teacher plans to test the null hypothesis that versus the alternative hypothesis , whererepresents the proportion of students who would pass the course using standard practice exercises andrepresents the proportion of students who would pass the course using adaptive practice exercises.The teacher knows that the percent confidence interval for the difference in proportion of students passing thecourse for the two practice exercise types (standard minus adaptive) is and the percent…arrow_forward3.
