\n" ); document.write( "\n" ); document.write( "Since f(x) is really \"y\", the transformation $\"k%28x%29=-f%28x%29\"$ reflects each y value to it's opposite $\"-y\"$ value. In other words, it takes a point like (0,1) and reflects it to (0,-1) (notice the y value is the opposite). So in general it takes (x,y) and reflects it to (x,-y)\r

\n" ); document.write( "\n" ); document.write( "So if P is (0,-1), then $\"k%28x%29=-f%28x%29\"$ will take the opposite of the y coordinate and reflect the point to (0,1)\r

\n" ); document.write( "\n" ); document.write( "So the new coordinates of P is (0,1) \n" ); document.write( "
