The diagonals if a rectangle are equal 1 always 2 sometimes 3 never

Remember that a rectangle has four equal angles, that the side lengths are equal and that the end lengths are equal. Under these circumstances the diagonals are of equal length.

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
