Iwould appreciate if anybody would me answer this question!

For this case what you should do is evaluate values of x in the function and verify that they meet the result of f (x) shown in the graph.
 
 f (x) = - lxl-2
 notice that
 f (3) = - l3l -2 = -5
 f (-3) = - l-3l -2 = -5
 Both comply with the value of f (x) shown in the third graph from left to right.

 answer
 third graph from left to right.

There is no graph to go along with this
