Question: An object is put outside on a cold day at time t = 0. Its temperature, H = f(t), in °C, is graphed in Figure.
(a) What does the statement f(30) = 10 mean in terms of temperature? Include units for 30 and for 10 in your answer.
(b) Explain what the vertical intercept, a, and the horizontal intercept, b, represent in terms of temperature of the object and time outside.
