Question

Which equations represent exponential growth?

Answer 1

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

Answer 2

A=20,000(1.08)^t is growth

A=80(1/2)^t is decay

A=1600(0.8)^t is decay

A=40(3)^t is growth

P=1700(1.07)^t is growth

P=1700(0.93)^t is decay

Explanation:

If n (the number in parentheses) is below 1, it is exponential decay.

If this same number is greater than 1, it is exponential growth.
