Logarithmic growth is a mathematical phenomenon whose size or cost can be described as a logarithm function of some input. It is the inverse of exponential growth and occurs in various fields such as computer algorithms, microbiology, and probability.
Learn how logarithmic growth differs from exponential growth and decay, and how to use the formula f(t) = A ⋅ log(t) + B. See an example of logarithmic growth applied to vocabulary size.
Learn how to model exponential growth and decay, use Newton's Law of Cooling, and choose an appropriate model for data. Explore applications of exponential and logarithmic functions in radioactive isotopes, population growth, and more.
While exponential functions exhibited fast growth (or decay), logarithmic functions exhibit slow growth (or decay). They all pass through the point \( (1,0)\), which makes sense because \( \log_a ( 1) = 0 \), as mentioned in the fun facts.
Learn the definition, evaluation, and graph of logarithmic functions, which are inverse of exponential functions. Logarithmic growth is the rate of change of a logarithmic function when the input increases by one unit.
Learn how to use logarithms to solve exponential equations and model population growth with a carrying capacity. Explore the properties of logarithms, the common log function, and the logistic growth equation.
Learn how to graph exponential and logarithmic functions, and how they differ in their properties and behaviors. See examples, definitions, key terms, and asymptotes of these functions.
Like the Exponential Decay model, the Gaussian model can be turned into an increasing function by subtracting the exponential expression from one and then multiplying by the upper limit. Logisitics Growth Model Function. y = a / (1 + b e-kx), k > 0. Features. Asymptotic to y = a to right, Asymptotic to y = 0 to left, Passes through (0, a/(1+b) )
Logarithmic regression is used to model situations where growth or decay accelerates rapidly at first and then slows over time. We use the command “LnReg” on a graphing utility to fit a logarithmic function to a set of data points.
Given a substance’s doubling time or half-time, we can find a function that represents its exponential growth or decay. We can use Newton’s Law of Cooling to find how long it will take for a cooling object to reach a desired temperature, or to find what temperature an object will be after a given time.
