\n" ); document.write( "An exponential function is of the form \"y+=+a%28b%5Ex%29\".

\n" ); document.write( "From the given information, we know
\n" ); document.write( "\"5+=+a%28b%5E0%29\"
\n" ); document.write( "\"5+=+a\"

\n" ); document.write( "Using that value of a with the other piece of information,
\n" ); document.write( "\"40+=+a%28b%5E3%29\"
\n" ); document.write( "\"40+=+5b%5E3\"
\n" ); document.write( "\"8+=+b%5E3\"
\n" ); document.write( "\"2+=+b\"

\n" ); document.write( "Both parameters for the exponential function have been determined. The function is
\n" ); document.write( "\"y+=+5%282%5Ex%29\"
\n" ); document.write( "
\n" );
