The function \(f(x)= -\frac{1}{20}(x-5)^3+\frac{1}{20}(x^2+4)\) is the formula for the height and slope of a training ski slope for small children. Its graph is shown below. The ski slope begins with a height of meters and has a length of more than decameters. The parents of the children stated that the slope is too steep at the bottom end and want the slope to stop at a height of 5 meters to be safer. What is the domain of the function to ensure the safety the parents want?
