A table of values of an increasing function F is shown. Use the table to find to find lower and upper estimates for integral^30 _10 (x) dx. Solution function is increasing x =4 lower estimate =x[f(10)+f(14)+f(18)+f(22)+f(26)] lower estimate =4*[-12-6-2+1+3] lower estimate =-64 ============================ upper estimate =x[f(14)+f(18)+f(22)+f(26)+f(30)] upper estimate =4*[-6-2+1+3+8] upper estimate =16.
