1. Advanced Algebra II Notes 4.5 Reflections and the Square Root Family
Reflection of a Function: A reflection is a transformation that flips a graph across a line, creating a mirror image. Given the graph of y = f(x): The graph of y = f(-x) is a reflection across the y-axis. The graph of y = - f(x) is a reflection across the x-axis.

2. The Square Root Function:
X value 1 2 4 9
Y value
Graph the functions:

3. d) y is replaced with (y – 2) e) y is replaced with (y + 2)

4. f) f( -x ) g) - f( x )
