This question talks about weather and how there is an actual temperature and the temperature you feel as a result of the wind chill factor. For example, the actual thermometer reading is 20 degrees, but, with the wind, it feels like 10 degrees.

The question goes on to give the function rule of F(T) = -52 + 1.6T, where T is the actual tempreature measured in degrees Fahrenheit, and can be used to estimate a wind chill tempreature at a speed of 40 mph.

a) What is F(32), and what does it mean in this context?

When I entered this into my calculator, the table value for y at 32 gave me about 52.2. Would this be right...? I'm not sure if I understand the basic concept of plugging in the 32.
