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

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.
