The graph gives the distance, d, in miles, you are from home as a function of time, t, in hours. O 39- We have d = f(t) 36- 33- Q a) Find f(0). 30- b) Use a line segment to represent the average E 27- rate of change of f(1) over the interval t, = 6 to 24- 21- 12 = 7 on the graph of d = f(t) 18- Distance, d c) Find and interpret the average rate of 15- change. 12- 6 ry a) f(0) = b) Refer to the segment on the graph A Distance, d (mi) Ad 39- O The value of - over this interval can be 36- 33- 30- represented by the of this segment 27- shown on the graph. 24. 21- 18- 15- 12- 9- 6- O- 1 (hr)
