The vertex of the graph $f(x)=4|x+6|$ is the point at which the function changes from decreasing to increasing.

Note that

for all $x$ the function is decreasing;
for all $x>-6$ the function is increasing;
at $x=-6$ the function has zero and this point is the point at which the function changes from decreasing to increasing.

Since at $x=-6$ the function has zero, then $f(-6)=0.$ This means that vertex has coordinates (-6,0).

Answer: (-6,0)
