Correlation coefficient ti 84.
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: y = abx. where: y: The response variable. x: The predictor variable.
