Answer:
D. (x, y) → (x, −y)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
The orientation shows how an object is arranged. Rotation, translation and dilation preserves orientation while reflection does not preserve orientation.
The transformation (x, y) → (4x, 4y) shows the dilation by a scale factor of 4. Dilation preserve orientation.
The transformation (x, y) → (−y, x) shows the rotation of a point 90 degrees counterclockwise. Rotation preserve orientation.
The transformation (x, y) → (14x, 14y) shows the dilation by a scale factor of 14. Dilation preserve orientation.
The transformation (x, y) → (x, −y) shows a reflection over the x axis. Reflection does not preserve orientation.
D = √(x2 - x1)^2 + (y2 - y1)^2) =
= √(6 + 1)^2 + (-2 - 4)^2) =
= √ (7^2 + 6^2) =
= √(49 + 36) =
= √85
Answer:
True
Step-by-step explanation:
For any function of the form 
the coefficient a produces a reflection of the function whenever 
.
We can verify it in the following way.
Take, for example, the function:
Now let's make 
Now let's in the following function:
We have:
We can see then that the function was reflected in the axis -y by placing a negative coefficient a.
You can see more examples in the attached images
Therefore we can conclude that the statement is true.
