How do you know whether the graph of f(x) = ax - h + k is a vertical stretch or a vertical shrink of the graph of f(x) = |x|? Select all statements that apply

Options:
If |a|>1 the graph is a vertical stretch
if |k|>1 the graph is a vertical stretch
if 0<|a|<1 the graph is a vertical shrink
if 0<|k|<1 the graph is a vertical shrink
