A continuous function h on [0,9] satisfies h′′(x)>0 for 0<x<4 and h′′(x)<0 for 4<x<9. Using three equal subintervals of length 3, both a midpoint sum M3 and a trapezoidal sum T3 are computed to approximate ∫09h(x)dx. Which approximation, M3 or T3, is likely to be closer to the true value of the integral? Briefly justify your choice.
