Study Notes
Reflection Rules
- Reflection across the x-axis is represented by the equation -f(x), which flips the graph over the x-axis.
- Reflection across the y-axis is denoted by f(-x), which flips the graph over the y-axis.
Shift Rules
- A horizontal shift to the left is expressed as f(x+a), moving the graph left by 'a' units.
- A horizontal shift to the right is shown as f(x-a), moving the graph right by 'a' units.
- A vertical shift upwards is characterized by f(x) + a, lifting the graph up by 'a' units.
- A vertical shift downwards is represented by f(x) - a, lowering the graph down by 'a' units.
Stretch Rules
- A vertical stretch occurs when the function is multiplied by a factor 'a' where a > 1, making the graph steeper.
