Respuesta :

Okay, here we have this:

Considering the provided graph, and that a function is decreasing when as x increases, "y" decreases, we obtain the following:

The intervals over which the function is decreasing are:

(infinity,-2)U(-2,-1)U(-1,1)U(5,infinity )

Finally we obtain that the correct answer is the option C.
