Reflections of Functions

Topic:: Functions, Reflection, Geometric Transformations

Use the sliders to transform y = f(x) into y = f(-x) and y= -f(x). Note how the new graphs relate to the original blue y = f(x) graph.

1. How is the graph of y = f(-x) obtained from the graph of y = f(x)? 2. How is the graph of y = -f(x) obtained from the graph of y = f(x)?
