Answer:
A. vertex, (3, 0); y-intercept 4.5
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex Â
( h , k ) . ( 3 , 0 )
To find the x-intercept, substitute in  0  for  y  and solve for  x . To find the y-intercept, substitute in  0  for  x  and solve for  y .
x-intercept(s): Â
( 3 , 0 )
y-intercept(s): Â
( 0 , 4.5 )
