y=0.00143x^4+0.00166x^3-0.236x^2+1.3x+0.739. Use a graphing calculator to fine tune this equation.
\n" ); document.write( "--------------
\n" ); document.write( "I can't even imagine what \"fine tuning\" an equation would mean.
\n" ); document.write( "Maybe it means you should find an appropriate WINDOW in the
\n" ); document.write( "calculator to see the important parts of the graph. If so
\n" ); document.write( "I find this window is good:
\n" ); document.write( "x-min = -17
\n" ); document.write( "x-max = 17
\n" ); document.write( "y-min = -32
\n" ); document.write( "y-max = 11
\n" ); document.write( "-------------------
\n" ); document.write( "Give that a try; see if it is \"fine tuned\".
\n" ); document.write( "Best wishes in teaching math.
