Study Notes
Graphing Radical Functions
- Involves representing functions on a graph that contain square root components.
- Important to reference the parent table for accurate values.
Radical Function
- Defined as ( y = \sqrt{x} ).
- Fundamental building block for graphing and understanding radical expressions.
Parent Table for Radical Functions
- Displays key (x, y) coordinates:
- (0, 0)
- (1, 1)
- (4, 2)
- (9, 3)
- Focuses on perfect squares for x values: 0, 1, 4, 9.
Interval Notation
- Tool to express the solution of inequalities.
- Domain (x-values): written as ([0, \infty)).
- Range (y-values): also expressed as ([0, \infty)).
Transformation of Radical Function
- General formula: ( Y = \pm a (\sqrt{x \pm h}) \pm k ).
- Modifications to the basic function alter its graph characteristics.
Transformation Function Elements
- ( \pm ): Indicates reflection over the x-axis.
- ( a ): Represents vertical stretch; affects the steepness of the graph.
- ( x \pm h ): Denotes horizontal shifts; determines left or right movement.
- ( \pm k ): Indicates vertical shifts; affects up or down positioning of the graph.
Starting Point of Radical Functions
- Originates from the first coordinate (c) and y-intercept in the parent table.
- Essential for understanding the graph's starting position.

- H: Horizontal Shift
- S: Vertical Stretch
- R: Reflection Over the X-axis
- V: Vertical Shift
- Useful mnemonic for remembering transformations of radical functions.
