A function has the property that each element of the domain maps to only one element. For example, if there's ever the case where a relation includes point (1,2) and (1,3) then that relation is not a function. So for each case write down all the points as described. If one point in the domain ever maps to two different points, then it's not a function
You can't prove that generalization is likely correct. <em />It is told that generalization is never correct and some has told that generalization is sometimes correct, so I guess that would depend on your thoughts, opinions.
hope this helped!!

Answer:
The value of 
= 
Step-by-step explanation:
Vertical Angle theorem: It is about the angles that are opposite to each other.
Also, vertical angle are congruent that means vertical angles are equal.
In the given figure; 
and 
are vertical angle
then, by vertical angle theorem, 
.
Supplementary angle: the sum of the angles whose measure on the straight line is 180 degree.
From the figure, , 
and 
forms a straight line.
then, by the definition of Supplementary angle;
Substituting the value of in above equation:
or
Simplify:
therefore, 
and 
,
the value of 
.
