Question

What model describes the relationship between the amount of bacteria and time, given that the bacteria quadruple every two hours?

linear
quadratic
cubic
exponential

Answer 1

For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount of bacteria
b: growth rate
t: time
Rewriting the equation for this case we have:
y = A * (4) ^ ((1/2) t)
Answer:
A model that describes the relationship between the amount of bacteria and time is:
exponential
