Question

I need to know which ones are Exponential Growth and Exponential Decay:
1. y = 0.63 (1.3)^x
2. y = f(x) = 2(0.65)^x
3. s(t) = 0.8 (1/8)^x
4. y = 12(1.7)6x
5. y = 5 (6)^x
6. y = 5/6 (0.45)^x

Answer 1

2 and 6 are decay as their rate is below 1. Anything below 1 is a decay. Anything above 0.99 is growth.

Answer 2

Thank you so much!
