a red triangle, a yellow rectangle, a green hexagon, and a red square
question: For the example given, what four shapes does X consist of?, context: For an example of a function, let X be the set consisting of four shapes: a red triangle, a yellow rectangle, a green hexagon, and a red square; and let Y be the set consisting of five colors: red, blue, green, pink, and yellow. Linking each shape to its color is a function from X to Y: each shape is linked to a color (i.e., an element in Y), and each shape is "linked", or "mapped", to exactly one color.  There is no shape that lacks a color and no shape that has two or more colors.  This function will be referred to as the "color-of-the-shape function".
