The graph of g(x) is obtained by reflecting the graph of f(x)=4|x| over the x-axis. which equation describes g(x)? a) g(x)=|x−4| b) g(x)=|x+4| c) g(x)=−4|x| d) g(x)=|x|−4

That would be choice C.

The graph of  4|x| is shaped like a V whose vertex is at the origin.

Every y value will be positive for y = 4|x|  as |x| is always positive  and a reflection in the x axis will make every y value negative.
