Question

Apply the dilation D to the polygon with the given vertices. Name the coordinates of the image points. Identify and describe the transformation.
D: (x,y) → (4x,4y)
A (2,1) B (4,1) C (4,-3)

a.This is a dilation about (0, 0) with a scale factor of 0.25; A’(8, 4), B’(16, 4), C’(16, –12).

b.This is a dilation about (0, 0) with a scale factor of 4; A’(8, 4), B’(16, 4), C’(16, –12).

c.This is a dilation about (0, 0) with a scale factor of 0.25; A’(0.5, 0.25), B’(1, 0.25), C’(1, –0.75).

d.This is a dilation about (0, 0) with a scale factor of 4; A’(0.5, 0.25), B’(1, 0.25), C’(1, –0.75).

Answer 1

b.This is a dilation about (0, 0) with a scale factor of 4; A’(8, 4), B’(16, 4), C’(16, –12).
