1. Why does the graph of the basic exponential function
\n" ); document.write( " $\"y+=+b%5Ex\"$ , where b>0, and b not 1) lie entirely above the x-axis?
\n" ); document.write( " $\"y\"$ is positive above the x-axis
\n" ); document.write( " $\"y+=+2%5Ex\"$ suggest b = 2
\n" ); document.write( "Now, plug some variables:
\n" ); document.write( "x = -1 . y = 1/2
\n" ); document.write( "x = 0 . y = 1
\n" ); document.write( "x = 1 . y = 2
\n" ); document.write( " $\"y\"$ always remains positive and greater than zero\r
\n" ); document.write( "\n" ); document.write( "2. Explain the difference between natural logarithms and common logarithms.
\n" ); document.write( "Natural logs: $\"log%28e%2Cx%29\"$ base of $\"e\"$
\n" ); document.write( "Common logs: $\"log%2810%2Cx%29\"$ base of $\"10\"$ \n" ); document.write( "

\n" );
