You can put this solution on YOUR website! open circle on -2, closed circle on 5, shaded in between ---> -2 < x <= 5
in roster notation: {-1, 0, 1, 2, 3, 4, 5} (integers between -2 and 5 as given by conditions)

The solutions by @CubeyThePenguin is INCORRECT.
I came to bring you the correct solution.
Since the line is solid between -2 and 5, it means that REAL NUMBERS are under consideration.
The correct answer is { x | -2 < x <= 5 }.
Solved.
