Question

A scientist is conducting an experiment on two types of bacteria to determine which type will grow faster in a pool. After collecting data for two weeks, she finds that she can model the growth rates as follows: Bacteria 1: y = 4x Bacteria 2: y = 4x2 In these models, y represents the number of bacteria colonies and x represents the number of hours. Based on these models, which type of bacteria is growing faster? bacteria 1

Answer 1

Answer:

bacteria 1

Step-by-step explanation:

hope this helped:)

Answer 2

Answer: bacteria 2

Step-by-step explanation:

Since the growth rates are modeled as : Bacteria 1: y = 4x

And Bacteria 2: y = 4x2

Where y represents the number of bacteria colonies and x represents the number of hours.

Let's plug in for the two models

By assuming x = 2 and x = 3

If x = 2

Bacteria 1 will be y = 8 and bacteria 2 will be y = 16

Based on these models, bacteria 2 is growing faster than bacteria 1 because the growth is exponential
