2.3, or 1⁄8, or it could be the negative versions of any of these numbers. so what can’t a be? it can’t be 3 or bigger than 3, and it can’t be –3 or less than –3.
okay, now it’s time to tackle . start by plugging choice (a), b = –8, into the equation. then . if you try some possible a values, you see that you can’t make this equation equal less than 4. the same thing happens when you plug in choices (b), (d), and (e). but if you try choice (c), you get . now if you let a = –2.5, or any number between –2 and
