The coordinates of the endpoints of the midsegment for △LMN that is parallel to LN are (3, 4.5) and (3, 3).
Explanation:
Given that △LMN
We need to determine the coordinates of the endpoints of the midsegment for △LMN that is parallel to LN
The midsegment of the triangle parallel to side LN is the midsegment connecting the midpoint of side LM and the midpoint of side MN.
The midpoint of LM is given by

Simplifying, we get,

The midpoint of MN is given by

Thus, the coordinates of the endpoints of the midsegment for △LMN that is parallel to LN are (3, 4.5) and (3, 3).
The first thing that comes to mind that an absolute value cannot have a nagative output, in other words, if you have an function that is equal to a negative number, then there is no solution.
Given: 

A.)Consider





Also,





Since, 
Therefore, both functions are inverses of each other.
B.
For the Composition function 
Since, the function
is not defined for
