Exponential Function:An exponential function has the form f(x) = a^x where "a" is any positive constant other than one.
Logarithmic Function: A logarithmic function has the form f(x) = log_a(x), where "a" is any positive constant other than one and log_a refers to taking logarithm base "a".
Natural Logarithm: The natural logarithm is a special case of the logarithm function with base e, denoted as ln(x).
