Answer:
Explanation:
Vertex form of a parabola:
where (h, k) is the vertex
Question 13
From inspection of the graph, the vertex is (-5, 4)
To find
, substitute the coordinates of a point on the curve into the equation.
Using point (-4, 5):
Therefore, the equation of the parabola in vertex form is:
Question 14
From inspection of the graph, the vertex is (2, -3)
To find
, substitute the coordinates of a point on the curve into the equation.
Using point (0, -5):
Therefore, the equation of the parabola in vertex form is:
