Question

A bacteria colony starts with 3 bacteria at the beginning and doubles every hour. How wouldyou write an explicit equation to model this situation?A f(x) = 2-3%B. f(x) = 3x + 2C f(x) = 2x + 3D. f(x) = 3.24

Answer 1

In this problem we have a linear equatiion of the form

f(x)=mx+b

where

m=2 -----> slope or unit rate

b=3 -----> initial value or y-intercept

substitute

f(x)=2x+3

therefore

The answer is

Option C
