A bacteria sample can be modeled by the function f(x) - 350(1.20) which gives the number of bacteria in the sample at the end of
marissa [1.9K]

Answer: A) The initial number of bacteria is 350.

Step-by-step explanation:

Exponential growth equation: f(x)=A(1+r)^x , where A=Initial value, r= growth rate.          (i)

Given: A bacteria sample can be modeled by the function f(x) = 350(1.20)which gives the number of bacteria in the sample at the end of x days.

Here, f(x)=350(1+0.20)

Compare this equation to  (i) , we get A = 350 and r= 0.20 = 20% (growth rate)

So, the  best interpretation of one of the values in this function are:

A) The initial number of bacteria is 350.
