The document contains code for three functions - cold(), warm(), and hot() - that take temperature values as input and output a value between 0 and 1 indicating how cold, warm, or hot the temperature is. The cold() function outputs 0 for temperatures at or above 35 degrees, a linear scale from 0 to 1 for temperatures between 20-35 degrees, and 1 for temperatures below 20 degrees. The warm() function is similar but for temperatures between 20-35 degrees. The hot() function outputs 0 for temperatures at or below 35 degrees, a linear scale from 0 to 1 for temperatures between 35-50 degrees, and 1 for temperatures at or above 50 degrees.
