The more close the value is to 1 the more accurate the model is. If one of the data points has the form. B 2 8 2 Divide both sides of the equation by 8 b 2 8 8 2 8 b 2 2 8.
The population of a species that grows exponentially over time can be modeled by.
Your exponential model was made by assuming that the best-fit exponential curve has no vertical or horizontal shift. 0 a displaystyle left 0aright 0 a then a is the initial value. Given two data points write an exponential model. The model with the higher R-squared is the better fit.
