Write f(x) = |x-1| + 2 as a piecewise function

Because K is on the left side of 0, it is negative. Therefore, the x-coordinate must be negative (the horizontal axis), and so we can rule out choices 3 and 4. The y-coordinate (the vertical axis) has to be 5/8. This is because 1/2 can be rewritten as 4/8, and 5/8 is exactly one unit above that. 3/4 does not work because K is too close to 1/2 to be 3/4, and 4/4 would not be able to reach one (with the set interval). Therefore, it is (-1/4, 5/8).
