(a)
Whether invariant points are sometimes, never or always maintained for the transformation described. If so describe the invariant points. If not, explain why the invariant points are not possible.
(a)
Answer to Problem 39HP
Sometimes.
Explanation of Solution
Given:Dilation of
Invariant points are the points that do not change during the transformation.
Here
The dilation is centered at the origin.
Therefore the points are sometimes invariant.
(b)
Whether invariant points are sometimes, never or always maintained for the transformation described. If so describe the invariant points. If not, explain why the invariant points are not possible.
(b)
Answer to Problem 39HP
Always.
Explanation of Solution
Given:Dilation of
Dilation with the scale factor
The points will remain same where they are regardless of the point of dilation.
The points are always invariant.
(c)
Whether invariant points are sometimes, never or always maintained for the transformation described. If so describe the invariant points. If not, explain why the invariant points are not possible.
(c)
Answer to Problem 39HP
Always.
Explanation of Solution
Given:Rotation of
The point
(d)
Whether invariant points are sometimes, never or always maintained for the transformation described. If so describe the invariant points. If not, explain why the invariant points are not possible.
(d)
Answer to Problem 39HP
Sometimes.
Explanation of Solution
Given:Reflection of
Reflection of
This is sometimes be true.
(e)
Whether invariant points are sometimes, never or always maintained for the transformation described. If so describe the invariant points. If not, explain why the invariant points are not possible.
(e)
Answer to Problem 39HP
Never.
Explanation of Solution
Given:Translation of
Translation of
Here,
The translation is never has invariant points as it will move the same direction and magnitude.
