Make AP Precalculus exponential modeling feel meaningful, hands-on, and worth the class time with this Holiday Café Cooling Lab! In this Unit 2 performance task, students collect real cooling data from hot water, transform the data by subtracting room temperature, build a vertically shifted exponential decay model, and interpret the model in context.This activity is designed to support AP Precalculus FRQ 2-style non-periodic modeling skills. Students solve for parameters (a) and (b), interpret a
