Do I need to find an exact model? Or will a regression model do?
In this webinar, we will explore different scenarios that require finding exact polynomial, exponential, or sinusoidal models; how to find them; and how they compare to their regression counterparts. Presenters will also highlight how to use TI technology to successfully find regression equations to model data and plot the corresponding residuals.
Join the live webinar for the chance to win a TI graphing calculator. (Download drawing rules.)
