Point of Diminishing Returns The revenue R(x) (in millions of dollars) generated from cattle farming can be approximated by the function R(x) = -3.21x' + 62.14x² + 172.92x + 48.65 %3D (0 < x < 14), where x represents the number of farms (in millions). What is the point of diminishing returns? (Data from: U.S. Department of Agriculture.)
