Students choose and interpret the scale on a graph to appropriately represent an exponential function.
Students plot points representing number of bacteria over time, given that bacteria grow by a constant factor over evenly spaced time intervals.
Problem Set Sample Solutions
1. Below are three stories about the population of a city over a period of time and four population-versus-time graphs. Two of the stories each correspond to a graph. Match the two graphs and the two stories. Write stories for the other two graphs, and draw a graph that matches the third story.3. Bacillus cereus is a soil-dwelling bacterium that sometimes causes food poisoning. Each cell divides to form two new cells every 30 minutes. If a culture starts out with exactly 100 bacterial cells, how many bacteria will be present after 3 hours?
