Answer:
Graph which have Focus ( 0 , 2) and Vertex = ( 0 , 0 ).
Step-by-step explanation:
Given : x² =8 y.
To find : Which graph represents the equation .
Solution : We have given that
x² =8 y.
On dividing both sides by 8
y = .
Vertex form of parabola y = a (x-h)² + k
Where, ( h ,k ) is vertex
h = 0 and k = 0
Vertex = ( 0 , 0 ).
a = .
Focus ( h , k + p).
p = .
p = .
p = 2
Then , Focus ( 0 , 2).
Therefore, Graph which have Focus ( 0 , 2) and Vertex = ( 0 , 0 ).
Answer:
Reflect over the y-axis
Step-by-step explanation:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).
Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis.
The reflection of the point (x,y) across
the y-axis is the point (-x,y).
