A table of values of an increasing function f is shown. x 0 5 10 15 20 25 f(x) 44 36 25 8 16 36 Use the table to find lower and upper estimates for the integral I. I = f(x)dx , endpoints [0,25]

Here is a hint: whether an estimate is upper or lower depends on which rectangles you use in the plane. The estimate is given by an expression of the form What should the values of be in each case?
