Question

A colony of amoebas is being studied. The mass of the colony triples every day. On Day x of the study, the colony has a mass of 3 ^ x mg. a. What is the mass of the colony on Days 3, 2 and 1? What is the mass of the colony on Day 0, when the study begins? Show your work .

Answer 1

mass on day 1: 3

mass on day 2: 9

mass on day 3: 27

Explanation:

using this equation, y = 3^x, you can plug in 1, 2, and 3 for 'x' to get the value of 'y' (which represents the mass on specific days)

3^1 = 3

3^2 = 9

3^3 = 27
