Sketch the curve

Question

y = x^3 - 12x^2 + 36x

I already did the question properly it is concave down at (0,4) and concave up at (4,infinity)

I found the abs max to be (2,32) and abs min to be (6,0)

What I wanted to know is when labeling the graph should I label the max/min as abs/local max or just abs max? I am having trouble figuring out if it is just an abs or a local.
