Explain why each function is continuous or discontinuous.
(a) The temperature at a specific location as a function of time.
(b) The temperature at a specific time as a function of the distance due west from New York City.
(c) The altitude above sea level as a function of the distance due west from New York City.
(d) The cost of a taxi fare as a function of the distance travelled.
(e) The current in the circuit for the lights in a room as a function of time.

latitude and proceed in a westerly direction, we can let 
denote the temperature at the point x at any given time. Assuming that T is a continuous function of x, show that at any fixed time there are at least two diametrically opposite points on the equator that have exactly the same temperature.
