We have the following function:

So if we graph this function we will get the Figure below. Thus, let's study both the equation and the graph to get some conclusions. Therefore, we can assure these statements:
First. The function is defined only for 

 as shown in the Figure. This is also true because of 

 where 

 must be greater (or equal) than zero.
Second. The range of the function are the values of 

.
Third. If 

 creases then 

 always creases, too. 
 
        
        
        
Answer:  y ≤ -x + 2
<u>Step-by-step explanation:</u>
There are an infinite number of possible solutions. 
Plot the two points, draw any line between them such that the two points are NOT connected, then choose the inequality symbol that shades (-1, 3). 
Here is one solution that satisfies the requirements.   y ≤ -x + 2
Here is another: y < -x + 3
And another: y > x + 3
And one more: y ≥ x + 4

10% of 26.80 = 2.68
5% of 2.68 = 1.34
2.68 + 1.34 = 4.02
Your best estimate is 4.05
