Question

Which of the following rules is the composition of a dilation of scale factor 2 following (after) a translation of 3 units to the right? A. (2x - 6, 2y)B. (2x - 3,2y)C. (2x + 3, 2y)D. (2x + 6, 2y)

Answer 1

Given:

Dilation of scale factor is 2.

Translationo of 3 units to the right.

The objective is to find the correct composition.

Consider the initial coordinatae of the graph as (x, y).

First for dilation of scale factor of 2, the coordinnate will be, (2x, 2y).

Following a translation of 3 units to othe right, the coordinate will be (2x+3, 2y).

Hence, option (C) is the correct answer.
