The transformations and their respective descriptions are:
A. (x, y) ⇒ (3x, y) implies horizontal stretch by a scale factor of 3
B. (x, y) ⇒ (x+3, y) implies translation 3 units right
C. (x, y) ⇒ (x, 3y) implies vertical stretch by a factor of 3
D. (x, y) ⇒ (x, y+3) implies implies translation 3 units up
E. (x, y) ⇒ (3x, 3y) implies dilation with a scale factor 3
<h3>What is Translation?</h3>
Translation is an algebraic transformation of a shape by moving the vertices some units along the x or y axis.
When a shape is translated it may move to a new position depending on the orientation of the translation.
Analysis:
For A, the x coordinate was transformed three times its initial value stretching it horizontally.
For B, the x coordinate moved 3 units further away from its initial value making the new value x+3 and y remaining the same.
For C, the y coordinated was transformed to a value three times what it was, making it to be stretched vertically, since the y-axis is a vertical axis.
For D, the y coordinate was moves 3 units away from its initial position making it to be translated up, since 3 is positive.
For E, both coordinates were stretched 3 units as much as their original value making the shape to dilate.
