Detailed explanation-4: -You can also calculate exponential growth using the formula f(x) = a(1 + r)x, where: The f(x) term represents the function. The a variable stands for the beginning value of your data. The r variable represents the growth rate.

Detailed explanation-5: -And while every population pyramid is unique, most can be categorized into three prototypical shapes: expansive (young and growing), constrictive (elderly and shrinking), and stationary (little or no population growth).
