Explanation:
I don't see any defined inequality here in the text.
but I can tell you what's in the picture. and how the correct inequality would look like.
the function, for which we need to define the range (all valid y-values) is moving between y = 2 and y = -2, including these 2 values.
the inequality shown is
-9 < y < -4
the values -4 and -9 are not included (indicated by the dotted lines).
so, we need to change that to
-2 <= y <= 2
please consider the "<=" signs, as both values have to be included, because the function is clearly also producing -2 and +2 values.
FYI
it would also be correct to write
2 >= y >= -2
