Warm UP 3/28/09 Describe the transformations of each graph: UP 3 REFLECT OVER X AXIS RIGHT 4 LEFT 2 DOWN 7
Practice Identify the parent function and the transformations for each equation: 1. 2. 3. 4.
It is also possible to look at a graph and determine the equation using the TRANSFORMATIONS! • What parent function is the graph related to? • Is the VERTEX moved up or down? • Is the VERTEX moved left or right? • Is the graph reflected over the x or y axis? • Is the graph stretched or shrunken?
Creative Time Create a dance for each equation below so that if you were to dance this equation, someone could guess which one you’re talking about.
Even and Odd Functions (algebraically) A function is even if f(-x) = f(x) If you plug in -x and get the original function, then it’s even. A function is odd if f(-x) = -f(x) If you plug in -x and get the opposite function, then it’s odd.
Even, Odd or Neither? Ex. 1 Graphically Algebraically EVEN
Even, Odd or Neither? Ex. 2 Graphically Algebraically ODD
Ex. 3 Even, Odd or Neither? Graphically Algebraically EVEN
Ex. 4 Even, Odd or Neither? Graphically Algebraically Neither
Your turn! Even, Odd or Neither? EVEN ODD
What do you notice about the graphs of even functions? Even functions are symmetric about the y-axis
What do you notice about the graphs of odd functions? Odd functions are symmetric about the origin
