@CLester13 So, do you have a better way to say, "f(x  2) = f(x + 2)"?

If you think like a philosopher, something = something right?

Or, something = something or something = something Which leaves JUST ONE POSSIBILITY: x  2 is the opposite of x + 2, right?

Okay, answer this thing when you come online: How do you represent this sentence  "the opposite of x + 2"?

I would square both sides of x2=x+2 so I wouldn't need to worry about the absolute value. So perhaps you know how to solve this: \[(x2)^2=(x+2)^2\] Hint: Expand both sides. You will be in for a real treat.
