Question

How is the pre-image(A) related to the image(B)?

• A. $3\leftarrow 1\uparrow$
• B. $3\leftarrow 2\uparrow$
• C. $3\leftarrow 1\downarrow$
• D. $2\leftarrow 2\uparrow$

Answer 1

The correct option is A $3\leftarrow 1\uparrow$

The pre-image A is moved 3 units horizontally leftwards and then 1 unit vertically upwards to reach B.
Thus, A is translated to B by $3\leftarrow 1\uparrow$
