Wording of a question: Inequalities
I have an issue with a wording of a question: It says 2 parts:
a) Sketch the graph of y = |2x-1|
This is easy enough but the next part:
b) solve the inequality |2x-1| <= 2 and check your result by examining the graph of y = |2x-1|
I think this means all the real numbers between -1 and 3 but if that is the case, how do you right this as an answer? Number line or descriptive as I just said.
Also am I on the right track?
Thank again for your help guys.
