Find the Vertex, the Y-Intercept, and the X-Intercepts (If Any $$r ( x ) = x ^ { 2 } - 6 x + 9$$

Find the vertex, the y-intercept, and the x-intercepts (if any exist) , and graph the function.
- $$r ( x ) = x ^ { 2 } - 6 x + 9$$

A)
Vertex $( 0 , - 9 )$
$x$ -int $= ( 3,0 )$ ,
$( - 3,0 ) ; y - i n t = ( 0 , - 9 )$
B)
Vertex $( 0,9 )$
no $x$ -intercepts;
$\mathrm { y }$ -int $= ( 0,9 )$
C)
Vertex $( 3,0 )$
$x$ -int $= ( 3,0 )$ ;
$y$ -int $= ( 0,9 )$
D)
Vertex $( - 3,0 )$
$x$ -int $= ( - 3,0 )$ ;
$\mathrm { y }$ -int $= ( 0,9 )$
