Exponential Function Growth (Continuous) - Equation to Scenario

Level 1

This math topic involves analyzing various real-world scenarios to match them with the appropriate exponential growth equations presented using continuous compounding. The problems include situations such as increasing downloads of an app, growth in a savings account balance, the expansion of a rabbit population, and the accumulation of credit card debt. Each problem presents an exponential growth equation and two possible scenarios, requiring the learner to select the scenario that fits the equation accurately. The focus is on understanding continuous growth rates (expressed as percentages) over specific periods.
