Question 1122095
Domain is (9, 25.5] for December
Range appears to be all real numbers >, although it isn't clear with arrows whether the lines keep going to positive infinity. Given that it is Celsius, there must be a positive limit, so from this graph, I would say the range is [-22, +6]. BE SURE THERE ISN'T MORE ON THIS GRAPH TO FINISH THE MONTH.  THERE MAY BE MORE INTERCEPTS AND MORE INCREASING AND DECREASING INTERVALS.
