How do you know that this was exponential decay? f ( x ) = 90 ( 1 2 ) x f\left(x\right)=90\ \left(\ \frac{1}{2}\right)^x f ( x ) = 9 0 ( 2 1 ) x

Because the 1/2 was less than one

Because the 90 was bigger than one

Because the 1/2 was bigger than one

Because the 90 was less than one

This function represents the number of ants in a colony f ( x ) = 3 ( 2 ) x f\left(x\right)=3\ \left(\ 2\right)^x f ( x ) = 3 ( 2 ) x What is the growth rate?

The ants are growing by 2 times

The ants are growing by 3 times

Classify the model as Exponential GROWTH or DECAY . $$A=10(1.01)^3$$

Growth $$y=a\left(1+r\right)^t$$

Decay $$y=a\left(1-r\right)^t$$
