Alyssa baked a cake and is waiting for it to cool so she can ice it. The table shows the temperature of the cake every 5 minutes after Alyssa took it out of the oven. Which model (linear, quadratic, exponential) best fits the data? How do you know? What is the best regression equation for this data? Alyssa will ice the cake when I reaches room temperature (70 degrees). Use the regression equation to predict when she can ice her cake.
