Rule for reflection over the y - axis,
( x , y ) ==> ( - x , y )
Rule for reflection over the x - axis,
( x , y ) ==> ( x , - y )
~~
Reflection over the y - axis,
A = ( 2 , 3 ) ==> A' ( - 2 , 3 )
B = ( 4 , 1 ) ==> B' ( - 4 , 1 )
C = ( 6 , 2 ) ==> C' ( - 6 , 2 )
D = ( 3 , 5 ) ==> D' ( - 3 , 5 )
Reflection over the x - axis,
A' ( - 2 , 3 ) ==> A'' ( - 2 , - 3 )
B' ( - 4 , 1 ) ==> B'' ( - 4 , - 1 )
C' ( - 6 , 2 ) ==> C'' ( - 6 , - 2 )
D' ( - 3 , 5 ) ==> D'' ( - 3 , - 5 )
~~
Another way to solve,
Reflection over the y - axis : Count the units away from the y - axis and then move that same amount pass the y - axis to reflect over the y - axis.
Reflection over the x - axis : Do the same for the x - axis yet count the units away from the x - axis and go that amount pass the x - axis.

Answer:
Opening: Opens upwards
Axis of Symmetry: -7/2
Vertex: (-7/2, -81/4)
X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
Step-by-step explanation:
Opening: 'a' is greater than zero
Axis of Symmetry:
Vertex:
X - intercepts:
(x-1)(x+8)
x = 1 and x = -8
Y - intercept: (0, -8)
It is a acute triangles because the degrees are less than 90 degrees
I don't really get what you are asking for. Can you clarify it?
Answer:
2 and 3 are the only true statements
