Graph the polynomial function. \[ f(x)=x^{3}-2 x^{2}-15 x \]

Step 1 ：Generate a range of x-values from -10 to 10.

Step 2 ：Calculate the corresponding y-values using the function \(f(x)=x^{3}-2 x^{2}-15 x\).

Step 3 ：Plot these points on a graph to represent the polynomial function.

Step 4 ：The graph shows the shape and behavior of the function across this range of x-values.

Step 5 ：\(\boxed{\text{The graph of the polynomial function } f(x)=x^{3}-2 x^{2}-15 x \text{ is plotted. The x-values range from -10 to 10 and the corresponding y-values are calculated using the function.}}\)
