2. 1. 2. Pg 175 # 40,42,44,46,48,49,52,95,96,97

3. Example 1 Classify each function as symmetric w.r.t. y-axis, origin or neither.

5. Even Functions

6. Odd Functions

7. Identifying even or odd functions Graphically (look for symmetry) symmetric w.r.t y-axis: even symmetric w.r.t origin (rotational symmetry): odd Algebraically If F(- x) = F(x), then is even. If F(- x) = - F(x), then is odd. Example 2 Graph the function. Find the symmetry and decide if the function is even or odd. Confirm algebraically. a. b. c.
