A polygon will be dilated on a coordinate grid to create a smaller polygon. The polygon is dilated using the origin as the center of dilation.
Which rule could represent this dilation?
(x, y) +(0.5-x, 0.5-y)

(x, y)+(x-7, y-7)
(x, y) + x, x, y)
(x, y) +(0.9 x, 0.9 y)

If g(x) is an odd function, which function must be an even function?
