What Is Humidity and How Does Humidity Affect Temperature?

The temperature-humidity index I (or humidex, for short) is the perceived air temperature when the actual temperature is T and the relative humidity is h, so we can write I=f(T, h). The following table of values of I is an excerpt from a table compiled by the National Oceanic & Atmospheric Administration. (a) What is the value of f(95,70) ? What is its meaning? (b) For what value of h is f(90, h)=100 ? (c) For what value of T is f(T, 50)=88 ? (d) What are the meanings of the functions I=f(80, h)
