For this case, we observe in the graph that the solution is given by:

$x <-2\ or\ x> 2$

Inequality does not contain equality because the boundaries of the solution are open.

Thus, we can discard options A and B.

From option C we have:

x ^ 2> 4

Applying root to both sides:

$x> \pm \sqrt {4}$

Thus, the solutions are:

$x> 2\\x <-2$

Answer:

Option C
