that means any value from -4 to -1 would be the answer....?

Yes any value from -4 to -1 would be he answer.

Would it not be -5 to -1, because it says greater then or equal to?

Why stop at -1? Nothing is said about p being an integer. Any $\displaystyle 0> x\ge -5$ satisfies "p is a negative number such that $\displaystyle p\ge -5$.

Here is the right answer to your question.

Be careful, your interval finishes with 0 as beyond they are positive...and you're looking for a negative.

Here are included all numbers between -5 and 0 (included -5)

Notice that you can get infinitely close to a number without reaching it. How?

Simply:

-4.99999...999...(and you'll never reach -5. In this case we do though)

-0.00000...000...1 (and you can spend the rest of your life placing zeros in between and never reach to 0)
