 # Even and Odd Functions

Videos and lessons with examples and solutions to help High School students to identify the effect on the graph of replacing f(x) by f(x) + k, kf(x),  f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Includes recognizing even and odd functions from their graphs and algebraic expressions for them.

Common Core: HSF-BF.B.3

Introduction to Odd and Even Functions
This video defines odd and even functions and provides 2 basic examples of odd and even functions.
Even Functions
• f(x) = f(-x)
• The graph is symmetrical across the y-axis
• A polynomial function will have all even exponents

Odd Functions
• -f(x) = f(-x)
• The graph has rotational symmetry about the origin
• A polynomial function will have all odd exponents.

Wolfram Even Odd Functions
This Demonstration allows you to look at the different types of even and odd functions.
Even functions: constant, absolute, consine, quadratic (square), exponential
Odd functions: identity, cube, sine, tangent.
