Graphs of Logarithmic Functions The logarithmic function is the inverse function to the exponential function. The logarithmic function is defined as f (x) = log a (x) where a, x ∈ R + and a ≠ 1. The ...

For example, suppose we want to solve the equation log_2 (x) + log_2 (x-4) = 3 for x. Using the multiplication rule of logarithms, we can rewrite the equation as: log_2 (x* (x-4)) = 3 Now, we convert ...

Exponential and logarithmic functions are mathematical concepts with wide-ranging applications. Exponential functions are commonly used to model phenomena such as population growth, the spread of ...
