Answer:

Step-by-step explanation:
One is given the following expression:

In order to simplify and solve this problem, one must keep the following points in mind: the square root function ( ) is a way of requesting one to find what number times itself equals the number underneath the radical sign. One must also remember the function of taking the square root of a negative number. Remember the following property: (

What is a function?</h3>
- A function is an expression that establishes the relationship between the dependent and independent variables.
- A function from a set X to a set Y allocates exactly one element of Y to each element of X. 
- The set X is known as the function's domain, while the set Y is known as the function's codomain. 
- Originally, functions were the idealization of how a variable quantity depends on another quantity.
To find the number of bacteria:
- The graph shows that the function follows an exponential curve, and the starting point is at ( 0,2.7 ). 
- The starting number of bacteria is then 2.7.
Therefore, there are (A) 2.7 bacterias initially.

The correct question is given below:
The growth of a strain of bacteria can be modeled by
the function graphed, where the x-values are the time
in seconds and the y-values are the number of
bacteria. How many bacteria are there initially?
(A) 2.7
(B) 2.8
(C) 4
 
        
             
        
        
        
(5280 vodas) * (1/2.71828 moloko/voda) * (1/3.1416 pivo/moloko) ≈ 618 pivos
(because 5280 has 3 significant digits)
