Does this table represent a function ? why or why not

C. No, because one x value corresponds to two different y values.

Step-by-step explanation:

We are given a table having value of x and y such that it forms a function.

Now, we know that a 'function' is a mapping from domain to the co-domain such that every value of the domain is mapped to a unique value of the co-domain.

According to our table, we can see that corresponding to the point x = 5, there are two different values y = 2 and y = 5.

So, this table does not represents a function.

Hence, option C is correct.

The answer is 4.

Step-by-step explanation:

Vertical Angles are congruent.

You plug in 4 for x and you multiply the two to get you 112.  

112-2=110, making the two angles the same angle measure.

Hope this helps :)
