The Heat Index, I, (measured in apparent degrees F) is a function of the actual temperature T outside (in degrees F) and the relative humidity H (measured as a percentage). A portion of the table which gives values for this function, I(T,H), is reproduced below:

T↓ \ H→	70	75	80	85
90	106	109	112	115
92	112	115	119	123
94	118	122	127	132
96	125	130	135	141

1. State the limit definition of the value ITT(94,75). Then, provide the best possible estimate for the value ITT(94,75), and write one complete sentence that carefully explains the meaning of this value, including units.

Solution:

2. State the limit definition of the value IHH(94,75). Then, provide the best possible estimate for the value IHH(94,75), and write one complete sentence that carefully explains the meaning of this value, including units.

Solution:

3. Finally, state the limit definition of the value IHT(94,75). Then, provide the best possible estimate for the value IHT(94,75), and write one complete sentence that carefully explains the meaning of this value, including units.
