The question says f(x) = |1−x| and asks for the graph of y = f(x). Well, that just
means the graph of y = |1−x|.
The smallest that y can be is 0, because the absolute value of anything is
nonnegative. That narrows the choices to (B) and (C). Notice that (D) and (E)
cannot be functions, because for some values of x, they show two associated
