Select all that apply.

• The image is smaller than the pre-image

• The image inverts through the center of dilation and appears on the opposite side.

• The image remains the same size

• The image disappears to the center of dilation

Draw

• (x, y) --> (0x, 0y)

• (x, y) --> (3x, 3y)

Multiple Choice

What kind of dilation is produced when a scale factor is greater than 1?

• The image remains the same size

• The image disappears to the center of dilation

• The image is larger than the pre-image
