WebSolve Exponentials for Time: Logarithms Reversing an Exponent. Earlier, we found that since Olympia, WA had a population of 245 thousand in 2008 and had been growing at 3% per year, the population could be modeled by the equation. P n = (1+0.03) n (245,000), or equivalently, P n n WebThe population exhibits exponential growth if b > 1 and exhibits exponential decay if 0 < b < 1. If b > 1, then the population size doubles after a time of T double = log 2 log b. If 0 < b < 1, then the population size halves after a time of T half = log 1 / 2 log b. Three doubling times T double or half-lives T half are illustrated by the blue ...
