Expert Solution
Step 1

.

y=\left(x-2\right)^2\left(x+4\right)

to find the x-intercepts take y=0

\left(x-2\right)^2\left(x+4\right)=0

\left(x-2\right)^2=0,\:\:\:\:\:\:\:\:\:\:x+4=0

x-2=0,\:\:\:\:\:\:\:\:\:\:x=-4

x=2,\:\:\:\:\:\:\:\:\:\:x=-4

{\color{Red} \mathrm{X\:Intercepts}:\:\left(2,\:0\right),\:\left(-4,\:0\right)}
