What is a linear function?
A linear function is a function where the variable has the highest degree of 1.
Given, A. The population of bacteria triples everyday. Therefore, it is an exponential growth function. Here, the growth is three times than the previous day.
B. The value of a cell phone depreciates at a rate of 3.5% each year. Here, it is an exponential decay function. The decay factor is 0.035 than the previous day.
C. An amusement park allows 50 people to enter every 30 minutes. Therefore, it is a linear function. Here, the number of people increases by 50 after every 30 minutes.
D. A baseball tournament eliminates half of the teams after each round. Here, it is an exponential decay function. The decay factor is 0.5 than the previous round.
