Problem #2: The heat index I is the perceived air temperature when the actual temperature is T and the relative humidity is H, that is, I = f(T,H). Consider the following table of values of I taken from a table compiled by the National Weather Service.

Use the table to find a linear approximation to the heat index function when the actual temperature is near 98°F
and the relative humidity is near 60%. Then estimate the heat index when the actual temperature is 99°F and the
relative humidity is 59%. (Note that IT(98,60) z 3 and I#(98,60) - 0.8.)
