Question

Which absolute value function, when graphed, represents the parent function, f(x) = |x|, reflected over the x-axis?

Answer 1

$y=-|x|$

The $a$ value of an absolute value parent function deals with vertical stretches or compressions and it's relation with the x-axis.

Changing the $a$ value to its negative counterpart will reflect the graph over the x-axis (as shown in the picture).

Hope this helps.
