Answer:

  A. ZE≅CE

  C. CD≅BA

Step-by-step explanation:

The first choice is absurd, because point E is not part of both triangles. It is obviously NOT TRUE.

However, we also find that choice C is NOT TRUE. Compare it to choice B, which is true.

Since no sides of the triangles are marked as congruent, choices B and C cannot both be right. Choice B involves corresponding segments; choice C does not.

For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.
snow_tiger [21]
We know that this is a parabola, as the equation is denoted by the x^2 term.

We can see that the symmetry is seen at the point -0.5, therefore making the axis of symmetry the vertical line -0.5.

The vertex is found in quadrant three. In other words, it will shift by a negative value both horizontally and vertically. The vertex is therefore (-0.5, -0.5).

We can verify this in the equations by using the formula (-b/2a) to find the vertex. The only quadratic equation that satisfies this is -2x^2 + 2x -1.

To sum it up, the answers are:

-2x^2 + 2x - 1.

AoS: x = -0.5

Vertex: (-0.5, -0.5).
