What kinds of
situations can be modeled with exponential
growth or exponential decay?

Step-by-step explanation:

Population growth is exponential.  Of people, rabbits (that's a big one!), and bacterial.  Decay is also exponential, and an example of that is radioactive decay.  This current situation of the corona virus is exponential, as well, at the rate at which people are currently becoming sick.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
