(B) 2E
(C) -
-E
(D)
(A)- E/2
​

Answer 1

Explanation:

The graph of a quadratic function is a U-shaped curve called a parabola. ... The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis.
