(1) The graph of f is given below. We want to evaluate 4 3 N X 2 (a) (10) Using the graphs above, identify the partition P over the interval [0, 2] and iden- tify the Ax. (b) (10) Fill in the blanks (where the "?"s are) for the following formulas. DO NOT EVALUATE THE FORMULA Uf ( P) = (f( ?) + f ( ? ) + f ( ? ) + f ( ? ) ) . ( ? ) and If ( P ) = (f ( ? ) + f ( ? ) + f ( ? ) + f ( ? ) ) . ( ? ) (2) Let f(x) = |x + 31. (a) (10) Sketch a graph of f. (b) (10) Using your graph, evaluate / f(x) dx
