Answer:
Step-by-step explanation:
We will use 2 coordinates from the table along with the standard form for an exponential function to write the equation that models that data. The standard form for an exponential function is
 where x and y are coordinates from the table, a is the initial value, and b is the growth/decay rate. I will use the first 2 coordinates from the table: (0, 3) and (1, 1.5)
 where x and y are coordinates from the table, a is the initial value, and b is the growth/decay rate. I will use the first 2 coordinates from the table: (0, 3) and (1, 1.5)
Solving first for a:
 . Sine anything in the world raised to a power of 0 is 1, we can determine that
. Sine anything in the world raised to a power of 0 is 1, we can determine that 
a = 3. Using that value along with the x and y from the second coordinate I chose, I can then solve for b:
 . Since b to the first is just b:
. Since b to the first is just b:
1.5 = 3b so
b = .5
Filling in our model:

Since the value for b is greater than 0 but less than 1 (in other words a fraction smaller than 1), this table represents a decay function.
 
        
             
        
        
        
Answer:
answer is c makes sense because you just add 1.25 x 20
 
        
             
        
        
        
Given:
The function is

To find:
The vertical asymptote of the given function. 
Solution:
Vertical asymptote are the vertical line passes thought the values for which the function is not defined.
To find the vertical asymptote, equate the denominator equal to 0.
We have,

Denominator is (x+2).


The vertical asymptote is  .
.
Therefore, the correct option is B.
