The graph shows the function f(x). on a coordinate plane, a cube root function goes through (8, 2), has an inflection point at (0, negative 1), and goes through (8, negative 3). which equation represents f(x)? f(x) = negative rootindex 3 startroot x endroot f(x) = negative rootindex 3 startroot x minus 1 endroot f(x) = negative rootindex 3 startroot negative x endroot minus 1 f(x) = negative rootindex 3 startroot negative x endroot
