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

What is the initial value for the function: f(x) = 300(1.16)^x?

• 300

• 1.16

• .16

• x
