\n" ); document.write( "Consider the function f(x)=-2x^2-8x+2 Find the Vertex.
\n" ); document.write( "
\"f%28x%29+=+-+2x%5E2+-+8x+%2B+2\"
\n" ); document.write( "x-coordinate of the vertex is at: \"x+=+-+b%2F%282a%29\"
\n" ); document.write( "\"x+=+-+-+8%2F%282+%2A+-+2%29\"
\n" ); document.write( "\"x+=+8%2F%28-+4%29\", or \"x+=+-+2\"\r
\n" ); document.write( "\n" ); document.write( "\"f%28x%29+=+-+2x%5E2+-+8x+%2B+2\"
\n" ); document.write( "\"f%28-+2%29+=+-+2%28-+2%29%5E2+-+8%28-+2%29+%2B+2\" ------- Substituting - 2 for x
\n" ); document.write( "\"f%28-+2%29+=+-+2%284%29+%2B+16+%2B+2\"
\n" ); document.write( "\"f%28-+2%29+=+-+8+%2B+16+%2B+2\"
\n" ); document.write( "\"f%28-+2%29+=+10\"
\n" ); document.write( "Vertex is found at the coordinate point: (\"highlight_green%28-+2%29\"\"%22%2C%22\"\"highlight_green%2810%29\") \n" ); document.write( "
\n" );
