What type of transformation is X Y to Y X?
This rotation can be described in coordinate notation as (x,y)→(y,−x) .
How do you describe transformations?
A transformation is a way of changing the size or position of a shape. Every point in the shape is translated the same distance in the same direction.
How do you describe reflection transformation?
A reflection is a transformation that acts like a mirror: It swaps all pairs of points that are on exactly opposite sides of the line of reflection. The line of reflection can be defined by an equation or by two points it passes through.
What is the rule for the reflection y x XY?
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).
What transformation is represented by the rule XY → X Y 3?
1 Expert Answer It is translation by 3 units up the y-axis.
How do you describe combined transformations?
Transformations can be combined by doing one transformation and then another. The three transformations that can be combined are reflection, rotation and translation.
How do you describe a translation?
A translation is a type of transformation that moves each point in a figure the same distance in the same direction. You can describe a translation using words like “moved up 3 and over 5 to the left” or with notation.
How do you describe a translation rule?
A translation is a type of transformation that moves each point in a figure the same distance in the same direction. The second notation is a mapping rule of the form (x,y) → (x−7,y+5). This notation tells you that the x and y coordinates are translated to x−7 and y+5. The mapping rule notation is the most common.
How do you describe fully the single transformation?
All students should be able to fully describe a single transformation using a rotation or translation. Most students should be able to fully describe a single transformation as a reflection, rotation or translation.
How do you write a transformation?
The function translation / transformation rules:
- f (x) + b shifts the function b units upward.
- f (x) – b shifts the function b units downward.
- f (x + b) shifts the function b units to the left.
- f (x – b) shifts the function b units to the right.
- –f (x) reflects the function in the x-axis (that is, upside-down).
