How does the exponential function work

The exponential function is a mathematical function of the form f(x) = a^x, where 'a' is a constant and 'x' is a variable. It is commonly used to describe the growth or decay of a quantity over time.
Exponential growth occurs when the value of 'a' in the exponential function is greater than 1, resulting in an increasing output as 'x' increases. On the other hand, exponential decay occurs when the value of 'a' is between 0 and 1, resulting in a decreasing output as 'x' increases.
The exponential function is used in various fields of science, such as biology, chemistry, physics, and economics. It is used to model population growth, radioactive decay, compound interest, and many other natural phenomena.
Some real-life examples of the exponential function include the growth of bacteria in a petri dish, the spread of a virus in a population, the decay of a radioactive substance, and the growth of a savings account with compound interest.
The exponential function and logarithms are inverse functions of each other. This means that for any given value of 'x', the value of the exponential function can be found using the logarithm, and vice versa. This relationship allows for easier calculations in solving exponential equations.
