Answer 2

To find the intersection of the two intervals (-8;6] and [-5;8), we need to determine the common values that belong to both intervals.

The first interval (-8;6] includes all numbers greater than -8 and less than or equal to 6, including -8 and 6: (-8; 6] = {-8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}

The second interval [-5;8) includes all numbers greater than or equal to -5 and less than 8, but it does not include 8: [-5; 8) = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7}

Now, we need to find the common values between these two intervals, which are the numbers that appear in both sets. From the above sets, the common values are:

Common values = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}

So, the intersection of the two intervals is [-5; 6].
