Question

Fix the inequality below to correctly show the domain of the function.

Note: to type an inequality like`\le`, type`<` then`=`

-9 < x < -5

Answer 1

To correctly show the domain of the function, you should express it in interval notation. The given inequality \(-9 < x < -5\) indicates that \(x\) is greater than \(-9\) and less than \(-5\).

In interval notation, this domain can be written as:

\((-9, -5)\)

This notation indicates that the interval is open, meaning \(-9\) and \(-5\) are not included in the domain.

If you prefer to keep it in inequality form, it remains:

\(-9 < x < -5\) (which is already correct).

So, either format is valid, but the interval notation is often preferred for expressing domains.
