Question 1 [9 points solutions and 1 point answer below]: Let f(x) = x3 + 9x2+ 15x - 4. a) [9 points] Use the 7 steps of Section 2.10 to construct the graph of f(x). b) [1 point] On your graph, if you only look at f(x) over the interval [-6, 1] then select the statement below that is true. Of(x) has only one absolute maximum and only one absolute minimum on [-6, 1]. Of(x) has two absolute maximums and only one absolute minimum on [-6, 1]. Of(x) has only one absolute maximum and two absolute minimums on [-6, 1]. Of(x) has two absolute maximums and two absolute minimums on [-6, 1]
