Which equations represent exponential growth?

To be honest any value inside the parentheses must be greater than 1 to have an exponential growth. Any value less than 1 will be a exponential decay

X>1 exponential growth
X<1 exponential decay

Exponential growth:

A=20,000(1.08)^t
A=40(3)^t
P=1700(1.07)^t

Exponential decay:

A=80(0.5)^t
A=1600(0.8)^t
P=1700(0.93)^t

Hope this helps

Um what? rephrase that ?

Ibelieve it’s b? hopefully
