Question

Identify if the given equation represents exponential growth or decay.

y = 2 • (1/3)^x

Identify if the given equation represents exponential growth or decay.
y = 3 • 2^x
​

Answer 1

The first is decay, seeing as it is in between 1 and 0

The second is growth, as it is greater than 1

Explanation:

It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.
