Answer:
1.) Exponential Growth
2.) Exponential Decay
3.) Exponential Growth
4.) Exponential Decay
Step-by-step explanation:
1.) f (x) = 0.5 (7/3)^x
↓
always increasing
2.) f (x) = 0.9 (0.5)^x
↓
always decreasing
3.) f (x) = 21 (1/6)^x
↓
always increasing
4.) f (x) = 320 (1/6)^x
↓
always decreasing
Step-by-step 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.
