Neet here again still learning algebra, now I'm learning about absolute value inequalities and how to graph them. I got a. and b. correct however for c I got the set of all real numbers (-infinity,infinity) in interval notation while the correct answer is (-5, 5) which is the intersection of x < 5 and x > -5. Shouldn't it be the union, which is my answer? I kept seeing the word "or" in examples.

Sorry if this makes no sense. I have zero understanding of mathematics. Just last month I couldn't add correctly.
