3. Shape of a Graph Below are the graphs of the first and second derivatives of a function f. Estimate the coordinate of the point of inflection and reconstruct the graph of f. You do not need to draw an exact graph but you need to reflect the following features: absolute and local extrema, intervals of monotonicity (increasing/decreasing), concavity, point of inflection. Briefly explain how you obtained your answer. 0.0 0.5 5.0 30 35 40 4550 4.5 -0.5 1.0 3.5...
