Consider the absolute value inequality |x - 3| > 2. Part 1: Using complete sentences, explain whether this inequality will be an "and" compound inequality (conjunction) or an "or" compound inequality (disjunction) and why. Part 2: Provide the solution to the inequality and describe the graph in complete sentences.
we write the absolut value inequality as follows.....-2< x-3<2
or 1 < x< 5
The value of x lies between a and 5....therefore this inequality is a conjunction
x is greater than 1 and less than 5
I'm not sure about the conjunction and disjunction, but I think the solution 1<x<5 given by @sandyjayaram is not correct. For example, let's try plugging in x=2. |x - 3| > 2 |2-3|>2 1>2 That is not true.
I think to get the solution, we can do it this way: |x - 3| > 2 We first break up the absolute value inequality into: (x-3)>2 and -(x-3)>2 Which simplifies into: x-3>2 and -x+3>2 x>5 and 1>x Thus those are the solutions.
I am sorry....i want to corect it
No problem @sandyjayaram , do you agree with my methodology?
yes i do
Nice. Kindly explain the conjunction and disjunction part if you can. I'm not sure about that.
ok...to find whether it is conjunction or disjunction we need to graph the solution
x < 1 , x >5 lets graph it
