The standard form of an exponential growth or decay equation is

f(x) = a(b)^x

What do each of the variables in this equation (a,b,x) represent?

Respuesta :

a: represents the initial amount (before the growth or decay starts).

b: represents the factor of growth or decay (e.g. 0.75 or 1.32).

x: represents the variable. This can be an amount of time (which is mostly true), or (sometimes) the other meaning of the variable is given.
