Exponential and Linear Growth

• Because the 90 was bigger than one

• Because the 1/2 was bigger than one

• Because the 90 was less than one

• Because the 1/2 was less than one

Classify the model as Exponential GROWTH or DECAY.

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
