Final answer:
The given function f(t) = 30(1.60)^t represents exponential growth as the number of plants increases by 60% each year.
Step-by-step explanation:
The given function f(t) = 30(1.60)t represents exponential growth.
In this function, t represents the time in years, and 1.60 represents the percentage increase per year (60%).
The function f(t) calculates the number of plants in Jericho's testing environment after t years, starting with an initial count of 30 plants. The exponential growth occurs because the number of plants increases by 60% each year, resulting in a larger count over time.
