The following questions refer to the table shown below, giving the temperature adjusted for wind-chill, $C$ , in ${}^\circ$ F, as a function $f(w,T)$ of the wind speed, $w$ , in mph, and the temperature, $T$ , in ${}^\circ$ F. The temperature adjusted for wind-chill tells you how cold it feels, as a result of the combination of wind and temperature.

	$T=35$	$T=30$	$T=25$	$T=20$	$T=15$	$T=10$	$T=5$	$T=0$
$w=5$	31	25	19	13	7	1	-5	-11
$w=10$	27	21	15	9	3	-4	-10	-16
$w=15$	25	19	13	6	0	-7	-13	-19
$w=20$	24	17	11	4	-2	-9	-15	-22
$w=25$	23	16	9	3	-4	-11	-17	-24

(a) Estimate $f_w(15, 30)$ :
$f_w(15, 30) \approx$
Be sure you can state in practical terms what your answer means.

(b) Estimate $f_T(20, 30)$ :
$f_T(20, 30) \approx$
Be sure you can state in practical terms what your answer means.
