What this Exponential Growth and Decay Models quiz checks
- Linear: equal differences in y. Exponential: equal ratios in y.
- In y = a · b^x, a is the initial value and b is the factor per step.
- Growth rate r gives b = 1 + r; decay rate r gives b = 1 − r.
- Compound interest once a year: A = P(1 + r)^t.
- Any exponential with b above 1 eventually exceeds any linear function.
The 10 questions of the quiz
- Which list of y-values (for x = 0, 1, 2, 3) shows exponential growth?
