\n" ); document.write( "The tutor @MathLover1 is 2/3 correct.
\n" ); document.write( "f(1) and f(2) are correct, but f(-1) is not.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To compute f(-1), you should use $\"f%28x%29+=+root%283%2Cx%29\"$ since that applies for $\"-1+%3C=+x+%3C+2\"$ which is where x = -1 resides. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "IF $\"x+%3C+-1\"$ was $\"x+%3C=+-1\"$ , then you would use the first piece. However, we don't have the \"or equal to\" portion.
