The depth of the submarine after M minutes is given by $\"+d%28m%29+=+-7500+%2B+80m+\"$
\n" ); document.write( "The limitations here are that $\"+d%28m%29+\"$ starts out at $\"+d%280%29+=+-7500+\"$ m and
\n" ); document.write( "rises, but , since it's a submarine, it can't go any higher than $\"+d%28m%29+=+0+\"$ . That
\n" ); document.write( "would put it above the water's surface.
\n" ); document.write( "----------------
\n" ); document.write( "Also the equation is set up for $\"+d%280%29+=+-7500+%2B+80%2A0+\"$ . Since the minutes can't
\n" ); document.write( "be less that $\"+m+=+0+\"$ , $\"+-7500+\"$ is the lowest depth that the equation can habndle
\n" ); document.write( "-----------------
\n" ); document.write( "Now I can chart these 2 positions, $\"+d%28m%29+=+-7500+\"$ , and $\"+d%28m%29+=+0+\"$
\n" ); document.write( "(1)
\n" ); document.write( " $\"+d%28m%29+=+-7500+\"$ meters
\n" ); document.write( " $\"+d%280%29+=+-7500+%2B+80%2A0+\"$
\n" ); document.write( " $\"+m+=+0+\"$ minutes
\n" ); document.write( "------------
\n" ); document.write( "(2)
\n" ); document.write( " $\"+d%28m%29+=+0+\"$ meters
\n" ); document.write( " $\"+0+=+-7500+%2B+80m+\"$
\n" ); document.write( " $\"+80m+=+7500+\"$
\n" ); document.write( " $\"+m+=+93.75+\"$ minutes
\n" ); document.write( "-----------------
\n" ); document.write( "So, the range is $\"+-7500+\"$ to $\"+0+\"$ meters
\n" ); document.write( "The domain is $\"+0+\"$ to $\"+93.75+\"$ minutes
\n" ); document.write( "--------------------------------------
\n" ); document.write( "Here's the plot:
