SOLUTION: what is the domain, range, increasing and decreasing intervals, intercepts and other important information. The graph below shows the curve of best fit that represents the low t

Question 1122095: what is the domain, range, increasing and decreasing intervals, intercepts and other important information.
The graph below shows the curve of best fit that represents the low temperatures for everyday in December in Denver, Colorado.

Also what are the key characteristics of the graph as it relates to the context of the problem.?

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)
