It's not a function because the x value repeated but wasn't accompanied by the same y value . there is (-2,2) and (-2,14) but if they had the same y value like (-2,2) and (-2,2) or (-2,14) and (-2,14) the table would represent a function. If you still dont understand I'll be more than happy to elaborate :)
X - 21.5 = <span>x less 21.5

Answer:
The statement is false.
Step-by-step explanation:
Let a and b represent two odd integers.
The average (A) is defined by:
A=![\frac{a+b}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%2Bb%7D%7B2%7D)
In order to prove the statement, you have to show that it's true for all odd integers. But, to disprove it, you just have to find a counterexample where the statement is false.
Notice that it is easier to try to find a counterexample.
For example, a=3 and b=5
A= ![\frac{3+5}{2} = \frac{8}{2} = 4](https://tex.z-dn.net/?f=%5Cfrac%7B3%2B5%7D%7B2%7D%20%3D%20%5Cfrac%7B8%7D%7B2%7D%20%3D%204)
The result of the average is even, therefore the statement is false.
The previous calculation is a counterexample.
sqrt(29) = 5.385
This means it is inbetween 5 and 6.
