Answer :
You have the correct domain. Nice work.
The range is incorrect.
The range is the set of possible y values that span from y = -2 (lowest part of the curve) to y = 4 (highest part)
Due to the open hole we exclude y = 4
The range as an inequality is -2 ≤ y < 4.
This would then condense to the interval notation [-2, 4)
