Give your answer in the form of a comma separated list, if ...In general, when a curve is concave down, trapezoidal rule will underestimate the area, because when you connect the left and right sides of the trapezoid to the curve, and then connect those two points to form the top of the trapezoid, you'll be left with a small space above the trapezoid. The small space is outside of the trapezoid, but ...

When a function is concave up, the second derivative will be positive and when it is concave down the second derivative will be negative. Inflection points are where a graph switches concavity from up to down or from down to up. Inflection points can only occur if the second derivative is equal to zero at that point.
