Solve the absolute value inequality. Express the solution using interval notation and graph the solution set.

i started it and i found that it doesnt come to nice numbers. but you know give a man a fish and he eats for a day but teach him to fish and he eats forever and such so. to do this you kinda just solve the equation. treat the absolute values as parenthases for the first answer and for the second answer you need to make the number inside the absolute value symbol negative. so just do it its not terribly difficult. fuck web assign i hate that shit.

I got something along those lines too, but I was using their reduced form. Despite this, I tried your answers anyways and they didn't work. I don't know if it is because they are truly wrong or webassign hates me, but anyways, I am over the guess limit, and I am stuck with wrong answers -.-

For some reason webassign wanted the answer to be -inf through +inf...totally wrong and our teacher said he was gonna just manually grade anything we put in there, unless we got it right to begin with...or something like that.

Anyways I pretty much got a 95 on the work...ill have to make it up with straight 100s from here on out because homework counts exactly as much as the final and midterm combined in this class.
