Because the x numbers are used more than once it cannot be a function. As for the the relation if its going through the origin then it would be a relation. im going to go with D
        
             
        
        
        
Answer:
x = 1
Step-by-step explanation:
When you subtract the smallest number from the biggest number, the answer is called the range. Here the largest number is 21. The smallest is 3. Then the range should be 18. But since it's 20. This mean that x is 1. Because 21 - 1 will equal 20, making 20 the range. So the correct answer is 1.

Answer:
Step-by-step explanation:
1.)1,2,3,4,5
mean=sum of all values/number of values
          =1+2+3+4+5/5
          =15/5
 mean=3
Mode :
In the given data, no observation occurs more than once.
Hence the mode of the observations does not exist, means mode=0.
Median 
1,2,3,4,5
Middle value is 3 so the median is 3.
2.)2,3,4,5,6,6
mean=sum of all values/number of values
          =2+3+4+5+6+6/6
          =26/6
mean =4.33 
Mode
       is that value of the observation which occurs maximum number of times so here mode is 6.
Median
2,3,4,5,6,6
  4+5/2
9/2
median=4.5
3.)6,7,5,4,5,6,2,5
mean=sum of all values/number of values
          =6+7+5+4+5+6+2+5/8
         =40/8
mean =5
Mode
 is that value of the observation which occurs maximum number of times so here mode is 5
Median
2,4,5,5,5,6,6,7
5+5/2
10/2
median=5
