Exponential Growth And Decay Worksheet Pdf With Answers
If you are a student of mathematics, you must have heard of exponential growth and decay. It is a fundamental concept in mathematics that finds its application in a broad range of fields, including science, economics, engineering, and finance. Exponential growth and decay refer to the behavior of a function with a constant ratio of change, either an increase or decrease over time. The concept is expressed mathematically using the exponential function, y = a * e^kt, where a, k, and t are constants, and e is the base of the natural logarithm.
What is Exponential Growth?
Exponential growth refers to the increase of a quantity over time with a constant ratio or rate of growth. This means that the amount of increase is proportional to the current value of the quantity. For example, if we have a population of bacteria that doubles every hour, the growth is exponential. The formula for exponential growth is y = a * e^kt, where k > 0, and a is the initial value of the quantity.
An exponential growth function has a positive slope and becomes steeper as time passes. This means that the rate of growth also increases with time. Therefore, exponential growth is characterized by rapid and uncontrolled increase, and it has many practical applications, such as the spread of infectious diseases, the growth of a company's profits, or the compounding of interest in the banking sector.
What is Exponential Decay?
Exponential decay refers to the decrease of a quantity over time with a constant ratio or rate of decay. This means that the amount of decrease is proportional to the current value of the quantity. For example, if we have a radioactive element that decays by half-life every hour, the decay is exponential. The formula for exponential decay is y = a * e^(-kt), where k > 0, and a is the initial value of the quantity.
An exponential decay function has a negative slope and becomes flatter as time passes. This means that the rate of decay also decreases with time. Therefore, exponential decay is characterized by a gradual decrease that eventually reaches zero, and it has many practical applications, such as the depreciation of assets, the decay of radioactive substances, or the reduction of pollution in the environment.
