First, decide whether you want to solve or evaluate the function. When the exponential function calculator is in "solve the function" mode: Decide the function formula shape (e.g., bxbx or p⋅ekxp⋅ekx). Give the exponential function calculator some x,yx,y points that you know are on...
and f(x) is an exponential function in terms of x. Also, note that the base in each exponential function must be a positive number. i.e., in the above functions, b > 0 and e > 0. Also, b should not be equal to 1 (if b = 1, then the function f(x) = bxbecomes f(x) ...
A function is evaluated by solving at a specific value. An exponential model can be found when the growth rate and initial value are known. An exponential model can be found when the two data points from the model are known. An exponential model can be found using two data points from a...
In our first example we will evaluate an exponential function without the aid of a calculator.Example Let f(x)=5(3)x+1f(x)=5(3)x+1. Evaluate f(2)f(2) without using a calculator. Show Answer In the following video we present more examples of evaluating an exponential function at ...
The second format—x1 / n— is what you’ll want to put into a graphing program or calculator. Some calculators do have nth root functions, like the Casio FX-9750G (press SHIFT and ). Examples The graph above shows an nth root function where n = 2. When n = 2, the function is ...
Example 4 AGAIN:(easier)Find an exponential function of the formf(x)= abxwhich will pass through the points (-3,256) and (2, ¼).Round to nearest hundredths if needed. We will solve this again, using theexponential regressioncapabilities of the graphing calculator. ...
This easy to use exponential moving average (EMA) calculator will allow you to calculate a data set's exponentially weighted moving average. To use the calculator, enter the data values, separated by line breaks, spaces, or commas, and click on the 'Calc

The geometric interpretation of the first "law" of exponents can then be stated as follows: iff(x)is some exponential function, then a stretch of the formkf(x)is equivalent to a translation of the formf(x+c). This is a property that can be observed on a graphing calculator or with ...
