Homework Help: Precal, Inequalities involving absolute value

  1. Jun 25, 2011 #1
    1. The problem statement, all variables and given/known data

    DIRECTIONS: Express the intercal in terms of an inequality involving absolute value.
    PROBLEM: (-4, 4)
    1: (-4, 4)
    2: -4<x<4
    3: |x|< 4 MY ANSWER
    Is that correct? Is step 3 correct? The only reason that I included that part is becuase it says "Involving absolute value," but I am not sure if that is what the question is really asking. Please advise if you can. Thank you in advance.

    hi name_ask17! :wink:

    yes, that's fine :smile:

    (and step 3 is obvious from step 1, you don't need step 2)​
