If P = (-1,-1), find the image
1 answer:
<h3>Answer: (-1, 1)</h3>
=========================================================
Explanation:
The rotation rule we use is
The x and y coordinates step places, then the second coordinate (after the swap) changes in sign from positive to negative, or vice versa.
For example, the point (5,7) rotates to (7, -5). As another example, (2,-1) becomes (-1, -2). As another example, (-9,4) becomes (4,9).
----------------------------------
In our case, the point (-1,-1) will rotate to (-1, 1)
Note: A 270 degree counterclockwise rotation about the origin is the same as a 90 degree clockwise rotation about the origin. Refer to the diagram below.

Answer : (8,5)
Given
K(x) =
Now we plug in each point and check whether it satisfies our equation
(-64,12)
K(-64) = = 12 so this point lie on graph
(125,3)
K(125) = = 3 so this point lie on graph
(343,1)
K(343) = = 1 so this point lie on graph
(8,5)
K(8) = = 6 so this point does not lie on graph because we got 6 instead of 5
