    Absolute Value Inequalities

    Hey all. Quick question as I have to get going...

    the homework question is to plot the inequality of "the absolute value of x is less than or equal to negative four" .... Am I right in putting a dot at 4 and -4, and a line in between?

    no, because the absolute value can't be negative!

    So there is no value of x.

    hmmmm... so this question is sort of like throwing 1 divided by zero at us.... There is no answer because you can't have a negative magnitude... Or.. maybe you can and this question is more like sqrt-1 where another means of finding an answer must be used.

    No, there is no answer.

    |n|\geq0 for any value n

    So |x|\leq-4 is impossible.
