Calculate the left Riemann sum for the given function over the given interval, using the given value of n. (When rounding, round your answer to four decimal places.)
f(x) = 35 − 105x over [−1, 1], n = 4

B) Calculate the left Riemann sum for the given function over the given interval, using the given value of n. (When rounding, round your answer to four decimal places.)

They gave you formulas for these. How far have you gotten in plugging the given information into the given formulas?

Please be complete. Thank you!
