    @Ashtaroth did you graph y = -2 and y=x^2-2x-1 on paper or a microsoft paint program?

    hmm... well y = -2 is a horizontal line and we can agree at that right? ^^

    so all we need to so is to graph y = x^2-2x-1

    The first one is A the second one is C and the last one is D. I've already picked B and it was wrong so i didn't bother publishing it.

    well that means we need to pick points. let x = 0,1,2, lalalalal but it's getting late so I'll just use desmos

    it's best to graph these equations on a piece of paper or some computer software before choosing... guessing isn't a good method.

    you have to understand the material and practice a lot. I used to fail miserably at Math and intentionally failed the COMPASS portion many years back, but with a few good mentors who can explain the topics well enough and with practice you'll be able to do any math problem :).
