Answer:
Option 3: 
Step-by-step explanation:
See the attached figure.
We will make a table for each function of the options, then compare each one of them with the given table.
So, we can deduce that the function of option 3: 
is the exponential equations could be represented by the table.
Note both of the given table and 
has Horizontal Asymptote y =2
Which mean as x→-∞ ⇒ y→2
