!!! Overview [1]
[{$pagename}] normally, is a [function] of the form:
%%prettify 
{{{
𝒇(x) = bⁿ
}}} 
/%
in which the input variable x occurs as an exponent.

A function of the form {\displaystyle f(x)=b^{x+c}, where c is a constant, is also considered an [{$pagename}] and can be rewritten as 𝒇(x)=ab^{x}, with a=b^{c}

[{$pagename}], as functions of a real variable, are uniquely characterized by the fact that the growth rate of such a function (i.e., its [derivative]) is directly proportional to the value of the function. The constant of proportionality of this relationship is the natural logarithm of the base b.
