Consider the graph of f(x) = 5x 6 – 5x 5 – x 4. On a coordinate plane, a graph decreases through (negative 0.6, 0.4), has an inflection point (0, 0), decreases through (0.5, negative 0.2) to (1, negative 1), and then increases up through (1.2, 0).

Based on the graph, what is the solution to
5x6 – x4 > 5x 5?
