open paren negative h comma k close paren
B
open paren h comma k close paren
C
open paren negative k comma h close paren
D
open paren k comma h close paren

Explanation

In f(x) = A|x − h| + k, the graph is shifted h units horizontally and k units vertically from the basic absolute value graph. Its vertex is therefore at (h, k), so the correct choice is (h, k).
