EVEN AND ODD FUNCTIONS

EVEN FUNCTIONS

DEFINITION even functions
A function $\,f\,$ is even if and only if for all $\,x\,$ in the domain of $\,f\,$,
$\,f(x) = f(-x)\,$.
for even functions:
when inputs are opposites, the corresponding outputs are the same





ODD FUNCTIONS

DEFINITION odd functions
A function $\,f\,$ is odd if and only if for all $\,x\,$ in the domain of $\,f\,$,
$\,f(x) = -f(-x)\,$.
for odd functions:
when inputs are opposites, the corresponding outputs are opposites



Master the ideas from this section
by practicing the exercise at the bottom of this page.

When you're done practicing, move on to:
extreme values of functions (max/min)
On this exercise, you will not key in your answer.
However, you can check to see if your answer is correct.
