The vertex, which is the turning point of the graph, in an absolute value function y = |x-h| + k, is represented by the point (h,k). To locate it, one should set the term inside the absolute value brackets to zero to get 'h'. Then, 'h' should be substituted back into the equation in order to determine 'k'.
