Answer:
The error was made when they factored out the i, so this would be the distributive property they did not do correctly.
Factoring out the i was never needed.
Answer:
Authoritarianism is a form of government in which the rulers, that is, those who exercise the political functions of the nation, carry out their tasks in an autocratic and centralized manner. Thus, they do not limit their power but, on the contrary, cling to it, at the expense of citizens' rights. A clear example of authoritarian governments that rule in Central Asian countries are Turkmenistan and Turkey.
A relation is the relationship between variables. When each input has one output, the relation is a function. When the value of k is 5 or 3, the relation will not be a function.
Given that:
![S= \{(2-|k+1|,4), (-6,7)\}](https://tex.z-dn.net/?f=S%3D%20%5C%7B%282-%7Ck%2B1%7C%2C4%29%2C%20%28-6%2C7%29%5C%7D)
For S, not to be a function, 1 domain element must point to more than one range elements.
This means that:
![2-|k+1| = 6](https://tex.z-dn.net/?f=2-%7Ck%2B1%7C%20%3D%206)
Collect like terms
![-|k+1| = 6 - 2](https://tex.z-dn.net/?f=-%7Ck%2B1%7C%20%3D%206%20-%202)
![-|k+1| = 4](https://tex.z-dn.net/?f=-%7Ck%2B1%7C%20%3D%204)
Multiply by -1
![|k+1| = -4](https://tex.z-dn.net/?f=%7Ck%2B1%7C%20%3D%20-4)
Remove absolute bracket
![k+1 = -4\ or\ k+1 = 4](https://tex.z-dn.net/?f=k%2B1%20%3D%20-4%5C%20or%5C%20k%2B1%20%3D%204)
Solve for k
![k =-1 -4\ or\ k= -1+4](https://tex.z-dn.net/?f=k%20%3D-1%20-4%5C%20or%5C%20k%3D%20-1%2B4)
![k =-5\ or\ k= 3](https://tex.z-dn.net/?f=k%20%3D-5%5C%20or%5C%20k%3D%203)
Hence, when k is 5 or 3, the relation will not be a function.
