The average revenue is defined as the function R(x) Ř(x) (x > 0) Prove that if a revenue function R(x) is concave downward (R"(x) < 0), then the level of sales that will result in the largest average revenue occurs when R(x) = R'(x). The average revenue is defined as the function R(x) Ř(x) (x > 0) Prove that if a revenue function R(x) is concave downward (R"(x) < 0), then the level of sales that will result in the largest average revenue occurs when R(x) = R'(x).
