Question

Direction of opening,vertex,equation of AOS,x-intercept (s),y-intercept,max/min value.

Answer 1

Answer:

Step-by-step explanation:

y = ax² + bx + c

- The graph of the parabola represented by quadratic function "y = a(x - h)² + k" has an axis of symmetry represented by equation of vertical line x = h ;

- If a > 0 , the parabola opens up;

- If a < 0 , the parabola opens down;

- The vertex is at (h, k).

~~~~~~~~~~

y = - (x + 2)²

1). Direction of opening: downward;

2). Vertex: (- 2, 0)

3). Equation of AOS (axis of symmetry): x = - 2

4). x-intercept: (- 2, 0)

5). y-intercept: (0, - 4)

6). Max / Min Value: Because graph is opening downward, the function has maximum value at the vertex y = 0
