Answer:
Ordinarily a graph like this will have arrowheads on the ends of the curve, indicating the curve continues on in the same direction. Here, we have to assume the existence of such arrowheads in order to choose a sensible answer.
As x goes to -∞, the curve continues to increase toward +∞. This is not an answer choice.
As x goes to +∞, the curve continues to decrease toward -∞. This matches the third answer choice.
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)
