Unformatted text preview: x ) is the graph of y = f ( x ) reflected about the x-axis. Reflections about the x-axis Reflection about the y-Axis The graph of y = f ( − x ) is the graph of y = f ( x ) reflected about y - axis. Example Use the graph of f(x)=x3 to obtain the graph of g(x)= (-x)3. y 4 3 2 1 x −4 −3 −2 −1 1 −1 −2 −3 −4 2 3 4 5 Example Use the graph of f(x)= x to graph g(x)=- x y 4 3 2 1 x −4 −3 −2 −1 1 −1 −2 −3 −4 2 3 4 5 Vertical Stretching and Shrinking Vertically Shrinking Vertically Stretching Graph of f(x)=x3 y 4 Graph of g(x)=3x3 y 4 3 3 2 2 1 1 x x −4 −3 −2 −1 1 −1 −2 −3 −4 2 3 4 5 −4 −3 −2 −1 1 2 3 −1 −2 −3 −4 This...
