Ascientist 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.

question 1) based on these models, which type of bacteria is growing faster?
question 2) how do you know which bacteria is growing faster?
(since i didn't see anyone ask this question, i will provide the correct answers as well. feel free to comment for free )
answer to question 1 is: bacteria 1
answer to question 2 is: an exponential function grows faster than a quadratic function.
