The a-value is the y-intercept (intial amount), and the b-value is the base. The base helps us to determine if the function is growth or decay. Which statement is true for decay?

• b>1

• 0<b<1

Given: f(x) = 300(1.16)^x , Marley wants to determine what the growth rate is. How could he do that?

• Find out how far 1.16 is from the number 1.00.

  1.16 - 1.00 = .16, so the growth rate is 16%.

• Convert 1.16 to a percent and get a growth rate of 116%.

• The rate is the a-value which is 300.
