EVEN FUNCTIONS
What is their common characteristic?
They have line symmetry over the y-axis.

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
