Question

bacterial growth over time
what is the population size at 6 hours—1000
between which hours does the population grow the fastest?—10 and 12
how much does the population increase from 2 to 10 hours?—about 4100 to 4200
if the trend continues, what might the population be at 14 hours?—12000 to 13000
what type of growth pattern does this represent (linear, exponential, or something else)?—

Explanation:

Step1: Identify population size at 6 hours

Read from the graph.

Step2: Determine fastest - growing interval

Check the steepness of the curve. Steeper means faster growth.

Step3: Calculate population increase from 2 to 10 hours

Read population values at 2 and 10 hours and subtract.

Step4: Predict population at 14 hours

Extend the trend of the curve.

Step5: Identify growth pattern

Observe the shape of the curve. The curve is getting steeper over time, which is characteristic of exponential growth.

Answer:

• Population size at 6 hours: 1000
• Fastest - growing interval: 10 and 12 hours
• Population increase from 2 to 10 hours: about 4100 - 4200
• Population at 14 hours: 12000 - 13000
• Growth pattern: Exponential
