ODD FUNCTIONS

What is their common characteristic?They have point symmetry about the origin.

EVEN FUNCTIONS

What is their common characteristic?

They have line symmetry over the y-axis.

Stretches & reflections do not change odd symmetry, but all other transformations do.

y = x4

EVEN y = x4 - 3 EVEN

Vertical shifts do NOT change even symmetry.

y = (x – 3)4 NEITHER

Horizontal shifts change even symmetry to neither.

Stretches and reflections do not change even symmetry.

Inverse Equations

• To graph– Make a table for the equation– Invert the x and y values to graph the inverse

• To write an equation– Switch the x & y variables– Solve– Look for restrictions
