Here's the plot of $\"+y+=+x%5E3+-+5+\"$
\n" ); document.write( " $\"+graph%28+400%2C+400%2C+-4%2C+4%2C+-10%2C+3%2C+x%5E3+-+5+%29+\"$
\n" ); document.write( "I would say it is a 1 to 1 function, because
\n" ); document.write( "there is 1 value of x for each value of y.
\n" ); document.write( "--------------
\n" ); document.write( "Here is a classic case of many values of x for
\n" ); document.write( "each value of y. It is $\"+y+=+sin%28x%29+\"$
\n" ); document.write( " $\"+graph%28+400%2C+400%2C+-10%2C+10%2C+-2%2C+2%2C+sin%28x%29+%29+\"$
\n" ); document.write( "It is not a 1 to 1 function \n" ); document.write( "
