Given the function:


f\mleft(x\mright)=(x+4)^2\left(x-2\right)^5(x-1\rparen

The x-intercept iswhen y =0, so:


\begin{gathered} x+4=0 \\ x+4-4=0-4 \\ x=-4 \\ \end{gathered}

And


\begin{gathered} x-2=0 \\ x-2+2=0+2 \\ x=2 \end{gathered}

And


\begin{gathered} x-1=0 \\ x-1+1=0+1 \\ x=1 \end{gathered}

Therefore, the x-intercepts are:

(-4, 0), (2, 0) and (1, 0)

Answer:

(-4, 0), (2, 0) and (1, 0)
