John inserts a partially used battery into a portable electric fan. The percent of the battery's total charge changes at a constant rate of -3.1% per minute since the fan was totally charged. a. Represent "an increase of 10 minutes in the amount of time the fan is used" from the given reference point on the graph. b. By how much will the percent of the total bot possible battery charge change when the fan is used for 10 minutes? Represent this on the graph. c. What is the percent of the battery's total f possible charge when the fan has been used for 17 minutes? Explain how you determined this value. Percent of total possible battery charge 100 80- 60 40 20 d. What is the vertical intercept of the graph of the function? Explain how you determined this value and represent your approach on the graph above. What does the vertical intercept represents in the context of this situation.
