Introduction
Calculus is one of the most intricate branches of mathematics that deals with the study of rates of change and continuity. A topic that forms a vital part of calculus is Exponential Growth and Decay, which deals with how certain quantities grow or decline over time. In this blog post, we will be discussing Exponential Growth and Decay in detail and how it is taught through Khan Academy.What is Exponential Growth?
Exponential Growth refers to the rapid and steady increase in the quantity of any given object or entity over a fixed period. This phenomenon is found in various natural and man-made settings, including population growth, spread of disease, inflation, and compound interest rates.Exponential growth is represented by a functions like y=ab^t, where a represents the initial quantity, b defines the rate of decay, while t represents the time taken.Example of Exponential Growth
For example, let us consider a population of bacteria that doubles every hour. The initial population at t=0 is 10. If we represent the population as y, we get y=10(2)^t, where t is the number of hours after starting. After the first hour (valued at t=1), the population of bacteria becomes 20, and after two hours, it becomes 40, thus showing exponential growth.What is Exponential Decay?
Exponential decay is the process of a quantity decreasing over time. This process is found in various fields, including radioactive decay, temperature, or a drug's effects on the body system.In the case of exponential decay, the function takes the form y=ab^(-kt), where a represents the initial quantity, b is the decay constant, and k is the decay rate.Example of Exponential Decay
Let's consider a particular radioactive isotope that decays exponentially. Suppose we start with an initial amount of 50 grams of the substance with a decay rate of k=10%. The function that models this could be given as y=50(0.9)t, where t is the number of years. After one year (t=1), the amount would have reduced to 45 grams.Exponential Growth and Decay Problems

Introduction
Exponential growth and decay are essential concepts in many areas of science, finance, and engineering. In calculus, we study these phenomena using exponential functions and derivatives. However, some students may find these topics confusing or challenging, especially when it comes to solving real-world problems. Luckily, there are plenty of resources available to help you master exponential growth and decay calculus, such as the Khan Academy website.What is Exponential Growth?
Exponential growth occurs when a quantity increases by a fixed percentage over a given time interval. For example, let's say you invest $1,000 in a bond that earns 10% interest per year. After one year, your investment will be worth $1,100 ($1,000 x 1.1). After two years, it will be worth $1,210 ($1,100 x 1.1), and so on. The formula for exponential growth is:f(x) = a(1 + r)^x
where f(x) is the function value at time x, a is the initial amount, r is the growth rate (expressed as a decimal), and x is the time interval.Example:
Suppose a population of bacteria has an initial count of 100 and doubles every hour. Find the equation for the population P(t) after t hours.P(t) = ab^t
therefore
P(t) = 100(2)^t
What is Exponential Decay?
Exponential decay occurs when a quantity decreases by a fixed percentage over a given time interval. For example, let's say you have a radioactive substance that decays at a rate of 5% per hour. After one hour, the amount of the substance remaining will be 95% of the initial amount. After two hours, it will be 90.25% (95% x 95%), and so on. The formula for exponential decay is:f(x) = a(1 - r)^x
where f(x) is the function value at time x, a is the initial amount, r is the decay rate (expressed as a decimal), and x is the time interval.Example:
The half-life of a certain radioactive material is 10 years. Suppose we have 1000 grams of this substance initially. Find the equation for the amount (in grams) that remains after t years.Let t represent the decay time, which means that there are t/10 half-lives.
The equation to find the remaining amount of radioactive substance A(t) in grams is given by:
A(t) = ab^t, where b = (1/2) (since the half-life is 10 years)
Therefore, A(t) = 1000*(1/2)^(t/10) grams.
Applying Calculus to Exponential Functions
In calculus, we study how the rate of change of a function changes over time (i.e., the derivative of a function). For exponential growth and decay functions, the derivatives are particularly useful for finding the slope of the function at any point, locating maximum or minimum values, and calculating related rates (e.g., velocity, acceleration). For example, the derivative of an exponential growth function f(x) = a(1 + r)^x is given by:f'(x) = ar(1+r)^(x-1)
The derivative of an exponential decay function f(x) = a(1 - r)^x is given by:f'(x) = -ar(1-r)^x
Tips for Solving Exponential Growth and Decay Problems
Here are some tips to help you solve exponential growth and decay problems:1. Identify the initial value (a), growth/decay rate (r), time interval (x), and other relevant variables given in the problem.2. Write the appropriate function formula (i.e., exponential growth or decay).3. Take the derivative of the function if necessary.4. Plug in the given values and solve for the unknown variable.5. Check your answer and make sure it makes sense in the context of the problem.Conclusion
Exponential growth and decay calculus may seem daunting at first, but with practice and patience, anyone can master the concepts. By using resources like Khan Academy, students can learn at their own pace and reinforce their understanding through practice problems and interactive tools. Remember to take things one step at a time, and don't be afraid to ask for help if you get stuck.

What is Exponential Growth and Decay?
Exponential growth refers to the phenomenon where a quantity increases at an increasing rate over time. This means that the more time passes, the faster the quantity grows. Conversely, exponential decay describes the progressive reduction of a quantity over time, with the rate of decay becoming slower as time goes on.
Mathematically, these concepts are expressed using exponential functions, which have the general form f(x) = ab^x, where 'a' is the initial quantity, 'b' is the growth or decay factor, and 'x' is time. The value of 'b' determines whether the function represents growth or decay.
