You have to consider the “ends” of the x-axis, the far right (for infinitely large values of x) and left (for infinitely small values of x) of the graph. 
From the diagram above you can see that:
- When  then then (notice that as the values of x get smaller and smaller, the graph gets closer and closer to the line y=1); (notice that as the values of x get smaller and smaller, the graph gets closer and closer to the line y=1);
- When  then then (notice that as the values of x get larger and larger, the graph gets closer and closer to the line y=1). (notice that as the values of x get larger and larger, the graph gets closer and closer to the line y=1).
Answer: correct choice is D.
 
        
             
        
        
        
Answer:
<em>In 5 years the product of their ages will be 208</em>
Step-by-step explanation:
The age of two children is 11 and 8 years.
Let's call x the number of years ahead.
We need to find when the product of their future ages is 208. The 11 years old child will be 11+x years old and the other child will be 8+x years, thus:
(11+x)(8+x)=208
Operating:

Simplifying:

Factoring:
(x-5)(x+24)=0
Solving:
x=5, x=-24
The negative solution is not valid, thus x=5
In 5 years the product of their ages will be 208
