if the growth rate is specified in centimeters per year, then a straight line equation appears to model it the best.
\n" ); document.write( "the number of centimeters per year is the slope.
\n" ); document.write( "your equation would be y = g * x + b where g is the number of centimeters of growth per year and b is the starting height.
\n" ); document.write( "this would lead to a straight line.
\n" ); document.write( "example:
\n" ); document.write( "growth rate is 5 centimeters per year for 3 years starting at 10 centimeters of height.
\n" ); document.write( "graph of that equation i shown below:
\n" ); document.write( " $\"graph%28400%2C400%2C-1%2C5%2C-1%2C29%2C5x%2B10%2C10%2C15%2C20%2C25%29\"$
\n" ); document.write( "horizontal lines were drawn at 10, 15, 20, 25 to show you the height of the trees in years 0, 1, 2, 3.
