- Types of transformations:
- Enlargement (stretch)
- Translation (movement)
- Reflection
- Tips
- Transformations outside the bracket affect the y-coordinates
- Transformations inside the bracket affect the x-coordinates
- When it is inside the bracket, think OPPOSITE
- f(x) - original graph
- f(x) + 21 - original graph has been translated up by 21
- f(x+21) - original graph has been translated left by 21
- 2f(x) - y-values have been stretched by scale factor 2
- f(2x) - x-values have been stretched by scale factor 1/2
- -f(x) - reflection of the y-values
- f(-x) - reflection of the x-values
