You can put this solution on YOUR website!
First pick a few values for $\"x\"$ , then see what
\n" ); document.write( " $\"f%28x%29\"$ is for that value. Make a little chart of these
\n" ); document.write( " $\"x\"$ and $\"f%28x%29\"$ combinations. Some good $\"x\"$
\n" ); document.write( "values to use are 0, 1 -1
\n" ); document.write( " $\"f%28x%29+=+3x+%2B+2\"$
\n" ); document.write( "-------------------
\n" ); document.write( " $\"f%280%29+=+3%2A0+%2B+2\"$
\n" ); document.write( " $\"f%280%29+=+2\"$
\n" ); document.write( "-------------------
\n" ); document.write( " $\"f%28-1%29+=+3%2A%28-1%29+%2B+2\"$
\n" ); document.write( " $\"f%28-1%29+=+-3+%2B+2\"$
\n" ); document.write( " $\"f%28-1%29+=+-1\"$
\n" ); document.write( "-------------------
\n" ); document.write( " $\"f%281%29+=+3%2A1+%2B+2\"$
\n" ); document.write( " $\"f%281%29+=+5\"$
\n" ); document.write( "-------------------
\n" ); document.write( " $\"f%280%29+=+2\"$
\n" ); document.write( " $\"f%28-1%29+=+-1\"$
\n" ); document.write( " $\"f%281%29+=+5\"$
\n" ); document.write( "These are the three points you can plot
\n" ); document.write( "------------------
\n" ); document.write( "You can also write them as
\n" ); document.write( "( $\"x\"$ , $\"y\"$ )
\n" ); document.write( "The three points are
\n" ); document.write( "( $\"0\"$ , $\"2\"$ )
\n" ); document.write( "( $\"-1\"$ , $\"-1\"$ )
\n" ); document.write( "( $\"1\"$ , $\"5\"$ )
\n" ); document.write( "There are lots of other oints you can plot, but these
\n" ); document.write( "are a good start. The graph looks like
\n" ); document.write( " $\"+graph%28+600%2C+600%2C+-6%2C+6%2C+-8%2C+8%2C+3x+%2B+2%29+\"$ \n" ); document.write( "
