\n" );
document.write( "corresponds to exactly one element of the domain.
\n" );
document.write( "Graphically one can use the horizontal line test to check for one-to-one
\n" );
document.write( "f(x)=2x^2+3x-5  this function is not a one-to-one function
\n" );
document.write( "   2 different values of x will result in the same y value.
