Answer: The inequality X ≤ 4 means that X can take any value less than or equal to 4, while the inequality X > -2 means that X can take any value greater than -2. To write this using interval notation, we start by writing the values that X can take as a set:
{X: -2 < X ≤ 4}
In interval notation, we write this set as:
(-2, 4]
