Also what are the key characteristics of the graph as it relates to the context of the problem.?
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! 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.
MIncreasing on [9, 12] and [16 and 22.5]
Increasing on [12, 16} and [22.5, 25.5]
No y-intercepts
x-intercepts at (10, 0), (16.5, 0) and (25, 0)
