Let $$f(x) = x-1\quad\hbox{and}\quad g(x) = 1-2x.$$
In the Figure above, match the colors of the graphs in this Figure with the functions given. Enter y for yellow, b for (dark) blue, r for red, p for purple, c for cyan (light blue), and g for green, as appropriate.

$y=f(x)$
$y = g(x)$
$y = (f+g)(x))$
$y = (f-g)(x))$
$y = (fg)(x))$
$y = \left(\frac{f}{g}\right)(x)$
