Answer:
Since x (independent) is time and y (dependent) is temperature;
F(0) =50 means; at the beginning which is 0 minutes, the temperature is 50F
f(120)>f(60) means the temperature after 120 min is bigger than the temperate after 60 min.
f(360) = f(345) means the temperature after 360 min and 345 min are the same
f(390) < f(360) means the temperate after 390 min is less than the temperature after 360 min
