we have
![f(x)=x^(3)-3x^(2) -4x](https://img.qammunity.org/2019/formulas/mathematics/middle-school/jobmnjpv5cc7bbedkh0zmamqmz96cu9ay1.png)
Using a graphing tool
The x-intercepts of the graph are the points
![(-1,0), (0,0),(4,0)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/mvwt0cl2itss9mzv85h6hzddx94yjd2wfm.png)
The x-intercepts are the values of x when the value of the function f(x) is equal to zero
