To get the range of the quadratic function, we first compute $\"%284ac-b%5E2%29%2F4a\"$ .
\n" ); document.write( " $\"%284ac-b%5E2%29%2F4a+=+%284%281%29%285%29-%28-7%29%5E2%29%2F4%281%29\"$
\n" ); document.write( " = $\"-7.25\"$
\n" ); document.write( "The coefficient of $\"x%5E2\"$ in $\"f%28x%29=+x%5E2-7x%2B5\"$ is positive therefore
\n" ); document.write( "the range is $\"y+%3E=+-7.25\"$ . \n" ); document.write( "

\n" );
