The graph cuts the x-axis at x=-4, -3 and -1.
The equation of the graph in the factored form can be written as,
[tex]\begin{gathered} f(x)=\lbrack x-(-4)\rbrack\lbrack x-(-3)\rbrack\lbrack x-(-1)\rbrack_{} \\ f(x)=(x+4)(x+3)(x+1) \end{gathered}[/tex]
Thus, the above expression is the required solution.
