f(t)=2t^2-4t-1
\n" ); document.write( "find f(2),F(-1
\n" ); document.write( "f(2)=2*2^2-4*2-1
\n" ); document.write( "f(2)=2*4-8-1
\n" ); document.write( "f(2)=8-8-1
\n" ); document.write( "f(2)=-1 answer.
\n" ); document.write( "f(-1)=2*-1^2-4*-1-1
\n" ); document.write( "f(-1)=2*1+4-1
\n" ); document.write( "f9-1)=2+4-1
\n" ); document.write( "f(-1)=5 answer. \n" ); document.write( "
