Answer:

4th choice (if we guessed the blurry letters properly)

Step-by-step explanation:

The reflection maps ...

(x, y) ⇒ (x -y)

Then the rotation maps ...

(x, -y) ⇒ (y, x)

That is, R(-1, 4) becomes R'(4, -1), apparently matching point S, the only point at (4, -1). We can't read the letters, but we know that you only need to know where R ends up in order to select the correct answer.

Using the given information, give the vertex form equation of each parabola.

WITCHER [35]

Answer:

Step-by-step explanation:

If you plot these points on a coordinate plane, you will see that they both lie on the same horiztonal line, y = -10, with the focus 1/4 to the right of the vertex. This information tells you a ton of stuff. First, it tells you that, since a parabola "hugs" the focus, this parabola opens to the right and is of the form x = y-squared. This equation is

$4p(x-h)=(y-k)^2$

The information also tells us that p (the distance between the vertex and the focus) is .25. h is the "x" coordinate of the vertex and k is the "y" coordinate of the vertex, so h = -1, and k = -10. Filling in our formula:

$4(.25)(x+1)=(y+10)^2$
