A scale factor of less than one means

• that the prime image will be larger than the pre-image.
• That the prime image will be the same as the preimage.
• That you need to subtract that amount off  of each side.
• That the prime image will be a reduction of the preimage.

How do you write the algebraic notation for a dilation from the origin with a scale factor of 3?

• (x, y) --> (1/3x, 1/3y)
