Answer:
6. y² = 169x
7. y² = 12x
8.
Step-by-step explanation:
The equation of a quadratic function in vertex form is given by
(y - α)² = 4a(x - β)
Where, (α,β) is the vertex of the function and a is the distance from vertex to its focus.
6. Here, (α,β) ≡ (0,0) and a point on the equation is (1,13)
So, the equation will be y² = 4ax
⇒ 13² = 4a(1)
⇒ 4a = 169
Therefore, the original equation will be y² = 169x (Answer)
7. Here also the vertex is (0,0) and a point on the equation is (3,-6),
So, (-6)² = 4a(3)
⇒ 4a = 12
So, the equation is y² = 12x (Answer)
8. Here also the vertex is (0,0) and a point on the equation is (),
So,
⇒
So, the equation is (Answer)
