How can you tell whether an exponential function models exponential growth or exponential decay?

Complete the explanation.

When the function is in the form () = , if the function models exponential growth, and if , the function models exponential decay.

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.

the answer is  

d.

121π mi^2
