Alright, so we have 14 degrees and -10 degrees. The difference between 14 and 0 is 14, and the difference between 0 and -10 is 10. 14+10=24 for total change. For the average over 8 hours, we have 24/8=3 degrees
On a graphing calculator, hit Math, Alpha, Math. Then input your logarithmic function. Hope this helped! Good luck :)
The answer is either A or D, B and C are off the table because the two shapes need to be graphed for those to be relevant. The answer you get should be A I believe.
