Which graph represents the function?

$\text{well the first thing I'd do is look at }-1 \leq x \leq 1\\ f(x) = |x-1| \text{ which decreases linearly from 2 to 0 on this interval}\\\text{That rules out the top left and bottom right graphs}$

$\text{Next I'd note that }f(8) = -2\\ \text{This rules out the bottom left graph}\\ \text{and thus the winner is the top right graph}$
