Answer
C
Work Step by Step
$A = {x | x > -1}$
$B = {x | -3\leq x \leq 2}$
If $x > -1, the solution area for both solutions overlaps over (-1, 2]. (This doesn't match answer A; however, this does match answer C.)
Answer B doesn't have an equals sign, which is needed. (A + A' makes the entire space.)
