Please help with this one question ASAP (Can you make it very organized and clear?)

A continuously increasing function that is concave up on the interval [0, 4] is represented by the table. X 0 1.9 2.1 3.4 4 f(x) -16 -12.39 -11.59 -4.44 0 Part A: Find the right Riemann sum estimate 1of ( x ) ax. using the subintervals given in the table. (10 points) Part B: Find the left Riemann sum estimate of Jo f(x) ax, using the subintervals given in the table. (10 points) Part C: Find the trapezoidal estimate of Jo f(x) ax. using the subintervals given in the table. (15 points) Part D: Determine whether the right Riemann sum estimate is an overestimate or an underestimate, based on the properties of the function. (5 points)
