You can put this solution on YOUR website!
I do not quite understand what you are asking, but I will guess this: how do I find answers by graphing? Simple, graph each side of the equation and at the x-value of the ordered pair where the graphed lines meet is your answer.
\n" ); document.write( "Ex.) x^2 - 1 = x^2
\n" ); document.write( "Red Line: x^2 - 1 = y
\n" ); document.write( "Green Line: x^2 = y
\n" ); document.write( " $\"graph%28300%2C300%2C-5%2C5%2C-5%2C5%2Cx%5E2-1%2Cx%5E2%29\"$
\n" ); document.write( "Since they never meet, there is no solution.
\n" ); document.write( "Ex.) x + 1 = x^2 + 1
\n" ); document.write( "Red Line: x + 1 = y
\n" ); document.write( "Green Line: x^2 + 1 = y
\n" ); document.write( " $\"graph%28300%2C300%2C-5%2C5%2C-5%2C5%2Cx+%2B+1%2Cx%5E2+%2B+1%29\"$
\n" ); document.write( "Intersect: P(0,1) and P(1,2)
\n" ); document.write( "x-values of points: 0 and 1
\n" ); document.write( "Answers: x = 0 and x = 1
\n" ); document.write( "Ex.) x - $\"pi\"$ = sin(x)
\n" ); document.write( "Red Line: x - $\"pi\"$ = y
\n" ); document.write( "Green Line: sin(x) = y
\n" ); document.write( " $\"graph%28300%2C300%2C-5%2C5%2C-5%2C5%2Cx+-+3.141592653%2Csin%28x%29%29\"$
\n" ); document.write( "Intersect: P( $\"pi\"$ ,0)
\n" ); document.write( "x-value of point: $\"pi\"$
\n" ); document.write( "Answer: x = $\"pi\"$ \n" ); document.write( "
