This lesson covers the concepts of even, odd, and neither functions, focusing on the function f(x) = x and f(x) = 2x² + 4. It reviews how to determine the nature of functions and also explores geometric translations. In geometry, translation involves moving a shape such that every point moves the same distance in the same direction. Students will learn to translate images by given points, such as (x – 8, y + 2) and (2x + 2, y – 3), and find the pre-image given a new point. Engage with classwork on transformations as functions for a deeper understanding.

Warm up Which one is even, odd, or neither? • f(x) = x • f(x) = 2x2 + 4 odd even neither
Translations In geometry, “translation” simply means MOVING
To translate a shape: Every point of the shape must move: The same distance In the same direction
