1.   Describe how the graphs of f(x) = |2x| and g(x) = -|2x| are related.
    A. The graph of g(x) is a reflection of the graph of f(x) over the x-axis. B. None are true.
    C. The graph of g(x) is a reflection of the graph of f(x) over the x- and y-axes. D. The graph of g(x) is a reflection of the graph of f(x) over the y-axis.
    Hint
