Question

Which graph represents the equation x^2 = 8y?

Answer 1

2 graph I think not certain

Answer 2

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 = $\frac{x^{2}}{8}$.

Vertex form of parabola y = a (x-h)² + k

Where, ( h ,k )  is vertex

h = 0  and  k = 0

Vertex = ( 0 , 0 ).

a = $\frac{1}{8}$.

Focus ( h , k + p).

p =  $\frac{1}{4a}$.

p =  $\frac{8}{4}$.

p = 2

Then , Focus ( 0 , 2).

Therefore, Graph which have Focus ( 0 , 2) and Vertex = ( 0 , 0 ).
