Understanding Exponential Growth and Decay: Exploring Euler’s Number in Mathematics

f(x)=eⁿ

In mathematics, the function f(x) = eⁿ represents the exponential function where e is Euler’s number (approximately 2

In mathematics, the function f(x) = eⁿ represents the exponential function where e is Euler’s number (approximately 2.71828) and n is a constant exponent.

To understand how this function works, let’s go over some key points:

1. The function includes the base e, also known as Euler’s number. Euler’s number is a mathematical constant similar to pi, used frequently in mathematical calculations involving growth, decay, and exponential functions. It is an irrational number and its value is approximately 2.71828.

2. The exponential function eⁿ represents a continuous, non-linear growth or decay over time. The constant n determines the rate at which the function increases or decreases.

Now, let’s look at some examples:

Example 1: f(x) = e⁰

When n is 0, the exponential function simplifies to e⁰, which equals 1. This means that for all values of x, the function f(x) will always be equal to 1.

Example 2: f(x) = e¹

When n is 1, the exponential function becomes e¹, which is equal to e itself. So, for any value of x, f(x) will be equal to Euler’s number, approximately 2.71828.

Example 3: f(x) = e²

When n is 2, the exponential function becomes e² which is approximately equal to 7.38906. This means that the function f(x) will increase more rapidly than in the previous examples as the value of x increases.

Example 4: f(x) = e⁻¹

When n is -1, the exponential function becomes e⁻¹ which is equal to 1/e. So, for any value of x, f(x) will be equal to approximately 0.36788. This represents a decay or decrease in the function as x increases.

Example 5: f(x) = e^x

In this general form, where n is represented as x, the function represents exponential growth. It means that for each increment in the value of x by 1 unit, the function value increases by a factor of approximately 2.71828.

Overall, the function f(x) = eⁿ involves exponential growth or decay depending on the value of the constant exponent n. The base e gives the function a special mathematical property, and the constant exponent determines the rate and direction of the function’s change as x varies.
