Answer:
1.
2.
3.
4.
Step-by-step explanation:
The vertex from of a quadratic function is
where, a is constant and (h,k) is vertex.
(1)
The vertex of the parabola is (-3,-4).
The graph is passes through the point (-1,0).
Therefore, the required equation is .
Similarly,
(2)
The vertex of the parabola is (-4,-3).
The graph is passes through the point (-3,-2).
Therefore, the required equation is .
(3)
The vertex of the parabola is (3,4).
The graph is passes through the point (2,5).
Therefore, the required equation is .
(4)
The vertex of the parabola is (4,3).
The graph is passes through the point (3,4).
Therefore, the required equation is .
