Question

Part 1: Assume that a bacteria population triples every hour. Which of the following three tables of data, with

x representing time in hours and y the count of bacteria, could represent the bacteria population? Circle the
letter of your choice.

Answer 1

Table C

If the bacteria population triples every hour, it must multiply by three each time.

Table C fits this pattern

y | 1 | 3 | 9 | 27 | 81 | 243 | 729

1×3=3, 3×3=9, 9×3=27 etc.
