Questions
- A population starts at 120 and grows by 8% each year. Which function models the population after t years?
- The model A(t) = 500(0.72)^t describes the amount of a substance remaining after t hours. What does the factor 0.72 mean?
- Which statement describes the graph of y = 3(2)^x?
- A quantity is multiplied by 3 whenever x increases by 1. Which table could represent this relationship?
- Put the steps for calculating the value of a model after 3 years in the correct order. The initial amount is 200 and it grows by 5% per year.
- Match each exponential model with its description.
- Complete the model using the initial amount and decay factor.
- Choose the correct descriptions to complete the statements about the graph.
- Sort each model into the correct category: exponential growth or exponential decay.
- Mark each statement true or false.
