The original value of a painting is $1400, and the value increases by 9% each year. Write an exponential growth function to model this situation.

y=1400(1.09)^x

y=1.09(1400)^x

y=1400(.91)^x

y=1.09^x

The population of Pallet Town increases by 15% every year. If there are currently 190,000 people living there, what will be the population in 13 years?

If necessary, round your answer to the nearest whole number.

4 people.

22,972 people.

Which of the following functions shows an initial amount of $15 and an increase of 35% each year?

y = 15(35)^x

y = 15(1.35)^x

y = 15(0.35)^x

y = 35(1.15)^x

The value of a car is $15,000 and depreciates at a rate of 8% per year. What is the exponential equation?

y=8(15,000)^x

y=15,000(1.08)^x

y=15,000(0.92)^x

y=15,000(0.08)^x

Your shiny new boat cost $7650. The depreciation for your boat is 14% per year. You want to know the value of your boat in 3 years. What is the equation that models this problem?

y = 7650(1 + 0.14)³

y = 7650(1 - 0.14)³

y = 7650e^(0.14)(3)

y = 7650 (1 + 0.14/12)^(12)(3)

11.

Write an equation that models the following situation:
Samantha's hair was known to grow very rapidly. It began at a length of 6 in and grew at a rate of 14% a week.

y=6(0.14)^x

y=6(1+14)^x

y=6(1.14)^x

y=6(0.86)^x
