You can put this solution on YOUR website!
**\"f%28x%29=f%28-x%29\" if they are even
\n" ); document.write( "**\"-f%28x%29=f%28-x%29\" if they are odd
\n" ); document.write( "**neither property is true if they are neither\r
\n" ); document.write( "\n" ); document.write( "An even function is a function where the same pattern is reflected on the y-axis. That means that for negative and positive x values, the y follows the same pattern. To figure out if they are even or not, plug in 1 for x, and see what you get. Then plug in -1 for x, and see what you get. If \"f%28x%29=f%28-x%29\" is true (if you end up with the same answer for both), then they are even. If you don't, then they are not even.
