Given the equation:


g(x)=x^3+6x^2+8x

To find the zeros of the graph, we will solve the equation: g(x) = 0

so,


x^3+6x^2+8x=0

Factor the equation to find the values of x:


\begin{gathered} x(x^2+6x+8)=0 \\ x(x+2)(x+4)=0 \\ x=0 \\ or,(x+2)=0\rightarrow x=-2 \\ or,(x+4)=0\rightarrow x=-4 \end{gathered}

so, the answer will be the zeros of the function are:


x=\mleft\lbrace-4,-2,0\mright\rbrace
