Graph transformations
Apply translations, stretches and reflections to graphs of functions; understand composite transformations
What you'll learn
- 1
Imagine a green squiggle drawn on a rubber sheet. When you stretch or squash the sheet, the squiggle changes shape — that's a transformation!
- 2
What does a graph transformation do to the original graph?
- 3
Let's transform y = x² by adding 3 outside: y = x² + 3
- 4
Drag the graph y = x² up by 2 units to see the new curve y = x² + 2.
- 5
If you have y = x² and you change it to y = x² + 5, what happens?
- 6
Now try a horizontal shift: y = (x - 2)²
- 7
What shift does y = (x + 4)² give?
