Answer
$(2,\infty)$.
The graph is shown below.
Work Step by Step
The given compound inequality is
$x\gt2$ or $x\gt4$.
First graph then take the union of the two inequality.
The graph is shown in the image file.
We can write the compound inequality.
$x\gt2$ as $(2,\infty)$ and $x\gt4$ as $(4,\infty)$
The union is
$(2,\infty)\cup(4,\infty)=(2,\infty)$.
