Marley’s cup of tea was cooling. Its temperature with relation to time can approximately be modeled by the function f(t) = 140(0.5)t + 72. Homework Help ✎
What does the 72 represent in this situation?
Marley decides to save energy and lower the temperature of her cottage to 68º. How would this change the model?
As t gets larger, the function value approaches 72.
Consider the significance of part b. Will the tea get cooler than surrounding air temperature?
f(t) = 140(0.5)t + 68
