\"f%28x%29=system%28+-x%3Ax%3C-1%2C++%0D%0A++++++++x-2%3Ax%3E-1%29\"
\n" ); document.write( "For problems like this, you have to determine which function applies by checking x against the limits of your function. In other words, is x greater than -1, or is x less than -1(I'm assuming that's what you meant or else your function is undefined between (x=-1) and (x=1)).
\n" ); document.write( "When x=-3/4, x >-1, so
