Which graph represents y = RootIndex 3 StartRoot x minus 5 EndRoot? On a coordinate plane, a cubic function has a point of inflection at x = 0 and crosses the x-axis at x = 5. On a coordinate plane, a cubic function has a point of inflection at x = negative 5 and crosses the x-axis at x = 2. On a coordinate plane, a cubic function has a point of inflection at y = negative 5 and crosses the x-axis at y = negative 5. On a coordinate plane, a cubic function has a point of inflection at x = 5 and crosses the x-axis at x = 5.
