Warm-Up: List the types of transformations and what each one means
Vocabulary
Transformations- Modifications in the size, position or direction of a graph or object.
Translation- A shift in position
Dilation/Compression- Shrinking or expanding the graph
Reflection- Reflecting an object across a line like a mirror image.
Activity
Essential Question
How do I graph vertical transformations?
Vertical Translation
gives a vertical translation of the graph The translation is k units up for k>0 and |k| units down for k<0.
Example 1
h𝐺𝑟𝑎𝑝 𝑦=𝑥2−3
Vertical Stretch/Compression gives a vertical stretch or vertical
compression If a>1, the graph is stretched vertically
by a factor of a If 0<a<1, the graph is compressed
vertically by a factor of a
Example 2
Graph
Example 3
Graph
Order for vertical Transformations1. Dilations/Compressions/Reflections2. Translation
Example 4: Write the equation and graph
Graph a cubic function that has a translation down 2 and a dilation of a factor of 3
