Notes Odd and Even functions What transformations represents an even / odd function? even function: Reflection of positive y values in the y-axis odd function: Rotation of positive y value 180 about centre (0, 0) Can you think of any functions that are even / odd?

Notes Even functions: f(x) = f(-x) Can you think of any? Think Pair share

Notes Odd functions: f(x) = - f(-x) Can you think of any? Think Pair share

WB 8 Determine whether the following functions are odd, even or neither: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Use a graph package to check / investigate
