Question 2

Answer 1

Given:

A dilation centered at the origin with a scale factor of 2 can be denoted

with the following notation:

$D_2(x,y)=(2x,2y)$.

To find:

The $D_4$ for point  A (-2, 3).

Solution:

If $D_2(x,y)=(2x,2y)$, then

$D_4(x,y)=(4x,4y)$

Substitute x=-2 and y=3 in the above rule to find $D_4$ for point  A (-2, 3).

$D_4(-2,3)=(4(-2),4(3))$

$D_4(-2,3)=(-8,12)$

Therefore, $D_4$ for point  A (-2, 3) is (-8,12).
