You can put this solution on YOUR website!
f(9) = 9, when x is less than or equal to 9, f(x) = x
\n" ); document.write( "f(18) = -3, when x is greater than 9, in this case, 18, then f(x)=-3
\n" ); document.write( "f(8) = 8, when x is less than or equal to 9, f(x) = x
\n" ); document.write( "this is called a piecewise function.
\n" ); document.write( "
\n" );
