A store receives 2,000 decks of popular trading cards. The number of decks of cards is a function, d, of the number of days, t, since the shipment arrived. Here is a table showing some values of d.

Calculate the average rate of change for day 0 to day 5

A store receives 2,000 decks of popular trading cards. The number of decks of cards is a function, d, of the number of days, t, since the shipment arrived. Here is a table showing some values of d.

Calculate the average rate of change for day 15 to day 20

• b>1

• b<1

• The average rate of change from year 0 to year 5 is less than the average rate of change from year 10 to year 15.

• The average rate of change from year 0 to year 5 is greater than the average rate of change from year 10 to year 15.

• a>0

Function f models the population, in thousands, of a city years after 1930.

The average rate of change of f from t = 0 to t = 70 is approximately 14 thousand people per year.

Is this value a good way to describe the population change of the city over that time period?

• Yes, every year it goes up by about 14 thousand

• No, the amount from one year to the next changes too much during this time span

• Yes, the amount changes every year

• No, the amount from one year to the next does not change
