algebra precalculus – solve the difference using a value table


Solve the difference using a value table
$frac{11}{2left(x+2right)}$ $le$ $1+frac{5}{2left(x+2right)^2}$

I dont understand how the table would look like $-2$ is odef and from $-1$ to $2$ is not true and only from $3$ to $infty$ is the difference true.
