Answer 1

What are the integer solutions of the inequality |x| < 4? This inequality involves the absolute value function, so solutions can be negative as well as positive.

Why not graph y=|x| first? Next, draw vertical lines thru the boundaries x=-4 and x=4.
Next, circle all of the integer x-values between (but not touching) -4 and 4.
