Rates of change, graphically For Exercises #1 and 2, use the graph of y = f(x) below 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 31 1. For each requested rate of change, sketch the line whose slope represents that rate of change. Carefully and legibly label each line with the part (la, 1b, 1c, 1d, le) which it represents, and then estimate its slope. Show work for full credit. a. The average rate of change of f from x =6 to x = 12 : b. The average rate of change of f from x =9 to x =10: c. The instantaneous rate of change of f at x =11 : d. The instantaneous rate of change of f at x =16 : e. Estimate the value of I with the greatest instantaneous rate of change of f for * in [0, co). Explain how you know
