You can put this solution on YOUR website!
y = a*b^x
\n" ); document.write( "3.5 = a*b^0
\n" ); document.write( "3.5 = a
\n" ); document.write( "~~~~~>
\n" ); document.write( "y = 3.5*b^x
\n" ); document.write( "56 = 3.5*b^2
\n" ); document.write( "16 = b^2
\n" ); document.write( "4 = b
\n" ); document.write( "~~~~~>
\n" ); document.write( "y = 3.5*(4^x) \n" ); document.write( "
