The vertex of the parabola below is at the point (-4,-2) wich of the equations below could be the one for this parabola

MrRissso [65]

The parabola with with a vertex at (-4,-2) represents any member of parabolas with the equation $y(x)=a(x+4)^2-2$ where $a$ is any real number with the exception that $a\neq 0$ .

The reason any equation of the form $y(x)=a(x+4)^2-2$ works is that there are an infinite number of parabolas with a vertex at (-4,-2). All of these parabolas are formed by applying some transformation that involves a vertical translation of -2 and a horizontal translation of -4 on the parabola $y=x^2$ . The different variations are archived by varying the constant $a$ . When $a$ is negative, the parabolas will face downwards. When $a$ is negative, the parabolas will be face downwards.

Which rays are part of line BE? Ac and O AB and AĖ AC and AB AB and F

Zanzabum

Answer:

We are given a diagram with different rays and lines.

Note: A line can be extend more and more upto infinitely length from both of the ends but a ray can be extend from end only.

We need to find the rays for the line BE.

We can see BE line has a point A in between line.

So, we can name the rays formed with end point A as AB and AE.

Therefore, AB and AE rays are part of line BE.

So, the correct option is 2nd option :

AB and AE.
