Question: When riding your bike in winter, the wind chill temperature is a measure of how cold you feel as a result of the induced breeze caused by your travel. If W represents wind chill temperature (in °F) that you experience, then W = f(T,v), where T is the actual air temperature (in °F) and v is your speed, in meters per second. Match each of the practical interpretations below with a mathematical statement that most accurately describes it below. For the remaining mathematical statement, give a practical interpretation. (i) "The faster you ride, the colder you'll feel."
(ii) "The warmer the day, the warmer you'll feel."
(a) fT (T,v) > 0
(b) f(0, v) ≤ 0
(c) fv(T,v)
