Which could be the graph of f(x) = |x - h| + k if h and k are both positive?
A- On a coordinate plane, an absolute value graph has a vertex at (2, 1).

B- On a coordinate plane, an absolute value graph has a vertex at (1, negative 4).

C- On a coordinate plane, an absolute value graph has a vertex at (negative 3, 2).

D- On a coordinate plane, an absolute value graph has a vertex at (negative 4, negative 5).
