Answer:

(-2, 8)

Explanation:

To express any given inequality, note the following:

✔️< or > means the end value or the beginning value referred to is not included.

✔️ ≤ or ≥ indicates that the end of beginning value is included.

✔️ "( )" when used in writing an inequality in interval notation means an end or beginning value is not included.

✔️. "[ ]" means the end or beginning value is included.

Now let's express -2 < x < 8 using interval notation.

✅The beginning value is -2, which is < x. This means -2 is not included. Therefore, we would start our interval notation by stating this as: "(-2"

✅The end value is 8. x < 8. The "<" sign means 8 is not included. Thus, this statement would be expressed in interval notation as "8)"

✔️Combining both together, the inequality is experessed in interval notation as (-2, 8)
