Exponential regression is a type of regression that can be used to model the following situations:. 1. Exponential growth: Growth begins slowly and then accelerates rapidly without bound. 2. Exponential decay: Decay begins rapidly and then slows down to get closer and closer to zero. The equation of an exponential regression model takes the following form:How to: Given a set of data, perform exponential regression using desmos. When using desmos, you will first, create a table and fill in the two columns with the data where the first column is x 1 and the second column is y 1.Then, type "y 1 ~ a b^x 1" and desmos will create the best fit exponential function and also give the values of a and b.Please make sure to check the box called "Log Mode ...The regression statistics will update automatically when you type new data into the table. Step 3: Plug your results into the equation. y = a * sin (bx + c) + d. For this example, we’re given the following results: Plugging those in, we get (rounded to two decimal places): y = 18.99 * sin (0.43x + 3.30) + 56.29.Explore math with our beautiful, free online graphing calculator.
