The table below gives the annual sales [in millions] of a product. 111115 11111 1111111 11211121 11111 IE m 331 1I1'11'hat was the average rate of change of annual saleS a} between 2'01? and 2013? b] between 201? and 21321? Find the average rate of change of f{.'} = 93:2 4 en the interval [4, I11]. Your answer will he an expression involving a. \fThe function e} = 23:3 3532 + 1921' | 3 has one local minimum and one local maximum. Use a graph {or table]: of the function to estimate these local extrema. (Hint: they occur between x = and x = 10} Round all answer to nearest integer. This function has a local minimum at z = |:' with output value: C] and a local maximum at :1: = |:] with output value: I:]
