How to use the Exponential Decay Calculator and Grapher The purpose of this grapher is to deepen the understanding of exponential decay functions by comparing two functions with different parameters. Enter initial amount A1 and the rate of decrease r1 (positive) for the first function a 1 (t) and the amount A2 and rate of decrease r2 (positive ...

Domain and Range: The domain of a general exponential growth function of a base to the exponent x is all real numbers, and the range is y is greater than or equal to 0. It is the same for a general exponential decay function. They both also have a horizontal asymptote at y=0. For more about domain and range, see the section entitled Functions.

Exponential Growth and Decay Functions An exponential functionhas the form y=abx, where a≠ 0 and the base bis a positive real number other than 1. If a > 0 and b> 1, then y=ab xis an exponential growth function, and bis called the growth factor. The simplest type of exponential growth function has the form y=b x. exponential function,p. 348

Exponential Function The general form of an exponential function is y = abx where the coefficient a is the y-intercept and the base b is the growth rate. Exponential growth and decay are both modeled with the general form y = abx. Growth is modeled by a base that is greater than 1, and decay is modeled by a base that is less than 1.

In this case, we say that the function describes exponential decay, and the constant \(b\) is called the decay factor. In Investigation 4.2, we consider two examples of exponential decay. Investigation 4.2. Exponential Decay. A small coal-mining town has been losing population since 1940, when 5000 people lived there.

More about Carbon Dating. In the 1940's Dr. Willard F. Libby invented carbon dating for which he received the Nobel Prize in chemistry in 1960. Carbon dating has given archeologists a more accurate method by which they can determine the age of ancient artifacts. The halflife of carbon 14 is 5730 ± 30 years, and the method of dating lies in trying to determine how much carbon 14 (the ...

Jul 15, 2017 · Third, the students will need to be slightly informed about exponential functions in order to make conjectures or determine theoretical functions as required in the worksheet. Fourth, going over how to use the calculator as directed prior to or during the activity may help the activity run more smoothly.

Exponential functions model many familiar processes, including the growth of populations, compound interest, and radioactive decay. Here is an example. In 1965, Gordon Moore, the cofounder of Intel, observed that the number of transistors on a computer chip had doubled every year since the integrated circuit was invented.
