The graph of the second derivative, FIX}, is given. Determine the x-coordinates of all points of inflection of x], if any. [Assume that x} is defined and continuous everywhere in [12, 12].} [HINT: Remember that a point of inflection off corresponds to a point at which f" changes sign from positive to negative or vice versa. This could be a point where its graph crosses the x-axis or a point where its graph is broken: positive on one side of the break and negative on the other] [Enter vour answers as a comma-separated list. If there are no points of inflection, enter DNE.) E12 3 4 4 12 The xy-coordinate plane is given. The curve enters the window in the third quadrant, goes up and right becoming less steepf changes direction at the point (4, 0}, goes down and right 5 heooming more steep, passes through the point [0, 4).. goes down and right becoming less steep, changes direction at the point (4, 8}, goes up and right becoming more steep, crosses the xaxis at x = 8, and exits 1e window in the rst quadrant
