Exponential Functions and Data Interpretation

The video tutorial covers various mathematical concepts, including calculating the average rate of change in trading card sales, understanding exponential growth in deer populations, analyzing city population changes, examining exponential growth in book sales, comparing bacterial population decay rates, modeling moth population decline, explaining R values, and interpreting graph intercepts.

What is the average rate of change in the number of trading card decks from day 0 to day 5?

• 200 decks per day

• 100 decks per day

• 77 decks per day

• 143.5 decks per day

From day 15 to day 20, how many decks were sold on average each day?

• 38 decks

• 143 decks

• 77 decks

• 50 decks

In an exponential growth function, what must be true for the population to increase?

• The growth factor b must be greater than 1

• The initial value a must be less than 0

• The growth factor b must be less than 1

• The initial value a must be greater than 1

What does a growth factor less than 1 indicate in an exponential function?

• The population doubles

• The population is increasing

• The population is decreasing

• The population remains constant

Why is the average rate of change not a good indicator for city population change over 70 years?

• It accurately models the data

• It shows a constant decrease

• It shows a constant increase

• It doesn't touch any data points

What happens to the population growth rate as time progresses in the city population model?

• It increases significantly

• It decreases significantly

• It remains constant

• It fluctuates randomly

For which domain is the average rate of change a good measure in book sales?

• 0 to 2 weeks

• 0 to 7 weeks

• 5 to 10 weeks

• 0 to 10 weeks

Why is the domain 0 to 10 weeks not suitable for average rate of change in book sales?

• It misses a lot of data

• It covers too little data

• It shows a constant rate

• It accurately models the data

Which bacterial population decays more quickly?

• The one with a growth factor of 2/3

• The one with a growth factor of 3/5

• The one with a growth factor of 1

• The one with a growth factor of 4/5

What is the initial population of the moths when first measured?

• 500,000

• 250,000

• 1,000,000

• 100,000
