Answer 2

It appears that you have provided two sets of intervals. Let me explain each of them:

1. Set 1: (-2, 3] This set represents all real numbers greater than -2 and less than or equal to 3. It is a closed interval, meaning that both endpoints (-2 and 3) are included in the set. Mathematically, it can be expressed as: (-2, 3] = {x | -2 < x ≤ 3}

2. Set 2: (-1, 5) This set represents all real numbers greater than -1 and less than 5. It is an open interval, meaning that the endpoints (-1 and 5) are not included in the set. Mathematically, it can be expressed as: (-1, 5) = {x | -1 < x < 5}

3. Set 3: (-10, -2] This set represents all real numbers greater than -10 and less than or equal to -2. It is a closed interval, meaning that both endpoints (-10 and -2) are included in the set. Mathematically, it can be expressed as: (-10, -2] = {x | -10 < x ≤ -2}

4. Set 4: [-7, 1) This set represents all real numbers greater than or equal to -7 and less than 1. It is a closed interval on the left side (includes -7) but an open interval on the right side (does not include 1). Mathematically, it can be expressed as: [-7, 1) = {x | -7 ≤ x < 1}

If you have any specific questions about these intervals or if you need further clarification, feel free to ask!
