You can put this solution on YOUR website!
Hint: Plug in the left endpoint x=-1 into f(x) to get some value. Make sure you take note of the sign of this value.\r

\n" ); document.write( "\n" ); document.write( "Now plug in the right endpoint x=0 into f(x) to get another value. Again, take note of the sign.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now if there was a sign change from f(-1) to f(0), then a zero exists in that interval. \n" ); document.write( "
