Sin² x + sin x = 0
sin x ( sin x + 1 ) = 0
sin x = 0       or     sin x + 1 = 0
x 1 = kπ,               sin x = -1
k ∈ Z                     x 2 = 3π/2 + 2 kπ,   k ∈ Z

Which of the following steps were applied to ABCD to obtain A'B'C'D?
Scrat [10]

Answer:

Option (A)

Step-by-step explanation:

In the figure attached,

Quadrilateral ABCD has been translated to get an image quadrilateral A'B'C'D'.

To get the rule by which the pre-image ABCD has been translated, we will choose a point A(1, 1) from the given pre-image.

Coordinates of point A' are (3, -2).

So the change is,

A(1, 1) → A'(3, -2)

A(1, 1) → A'[(1 + 2), (1 - 3)]

A(x, y) → A'[(x + 2), (y - 3)]

Therefore, point A has been shifted 2 units right and 3 units down.

Option (A) will be the answer.
