The Lake of Distress is contaminated with flesh-eating bacteria!! The lake started with only 4 square feet infected, but as time has gone on, the bacteria are growing by a factor of 3 every hour. Assume that the relationship between hours and square feet of bacteria is continuous.

The relationship is …

• A sequence because there is a pattern of multiplying by 3 every hour

• A sequence because there is a pattern of adding 3 every hour

• Not a sequence because there is no pattern

• Not a sequence because it is continuous
