Plot the graph of equation y=x(6-x)

Since the graph will be an inverted parabola open downwards (i.e. y will be less than x(6-x) for points to be inside the parabola) therefore any point for which y<x(6-x) with positive value of y will be surrounded by the graph and x-axis (as shown in figure)

All points are surrounded as shown in figure and satisfied by (red highlighted equation). Hence,
