Answer:

Step-by-step explanation:

We can eliminate answer choices by looking at several factors. If the parabola opens upward, there cannot be a negative number as 'a'. Recall that standard form of a parabola is y= ax² + bx + c.

Therefore, any choice that has a negative number as 'a' opens downward. This leaves answers A and C.

Next, for the parabola to appear narrower, it must have some kind of vertical stretch or horizontal compression. 'A' is the only choice that has a vertical stretch transformation done to the parabola. The correct answer is A.

Answer:

Given, DF and DE are midsegments of ABC. so D is the mid point of AB and F is the mid point of AC.

Considering AB,

Then DE is parallel to AC, as mid-segments are parallel to the non included side of the triangle.

Also, according to corresponding angle theorem,

Then,

As,

According to similarity of two triangles,
