Question

PLS Help me! This graph shows the outside temperature (in degrees Celsius) over the course of 12 hours, starting at midnight (x = 0). What is the domain? What does the domain mean in terms of the problem? What is the range? What does the range mean in terms of the problem? When is the function decreasing? What does this decreasing interval mean in terms of the problem?

Answer 1

Answer:

The domain is the set of all possible x-values

• Domain is the time here

The range is the resulting y-values

• The range is the outside temperature is here

• Function is decreasing between x= 0 to 3

• It means the temperature is decreasing between midnight and 3 AM
