Given the function f(x)=-2c+cx-x² and f-1(3)=-1, find c
\n" ); document.write( "
\r\n" );
document.write( "f-1(3)=-1 simply means that f(-1) = 3\r\n" );
document.write( "\r\n" );
document.write( "f(-1) = -2c+c(-1)-(-1)²\r\n" );
document.write( "\r\n" );
document.write( "    3 = -2c-c-1\r\n" );
document.write( "    3 = -3c-1\r\n" );
document.write( "   3c = -4\r\n" );
document.write( "    c = -4/3\r\n" );
document.write( "\r\n" );
