Study Notes
Graphing Quadratic Functions
- Involves understanding transformations, standard form, vertex form, and key characteristics of a parabola.
Types of Transformations
- Includes translation (shifting graph), vertical stretch (increasing steepness), vertical compression (decreasing steepness), and reflection (flipping the graph).
Translation Up
- Defined mathematically as f(x) = (x) + n, shifting the graph upward by n units.
Translation Down
- Represented as f(x) = (x) - n, shifting the graph downward by n units.
Translation Left
- Expressed as f(x) = (x + n), which moves the graph left by n units.
Translation Right
- Formulated as f(x) = (x - n), moving the graph right by n units.
Vertical Stretch
- Occurs when a > 1, affecting the steepness of the graph, defined as f(x) = (a > 1)(x).
Vertical Compression
- Happens when 0 < a < 1, reducing the steepness of the graph.
