Answer:

c

Step-by-step explanation:

252 = 7 *36

36 = 6 *6 = 6²

a² -b²  = (a + b)(a - b)

7h² - 252k² =  7(h² - 36k²)

                   = 7(h² - [6k]² )

                  = 7(h  +6k)(h - 6k)

The domain is all the x-values you can use with this function. When dealing with a function like this, you need to ask yourself, what would make the bottom equal to 0? Whatever those numbers are, you do NOT want them in your domain.

A fundamental rule is that you cannot divide by 0 or have 0 as a denominator.

So, you solve x^2+6x=0 to find that x=0 or x=-6 would make the denominator 0.

The domain is everything BUT those two values, because they essentially break your function.

The image of rectangle JKLM after a reflection over the y-axis around the origin is J = (6, -2), K = (6, -1), L = (0, -1) and M = (0, -2)

<h3>How to graph the image of rectangle JKLM after a reflection over the y-axis around the origin?</h3>

From the graph, the coordinates of the rectangle are:

J = (-6, -2)

K = (-6, -1)

L = (0, -1)

M = (0, -2)

The rule of a reflection over the y-axis around the origin is

(x, y) = (-x, y)

When the above rule is applied, we have the image to be:

J = (6, -2)

K = (6, -1)

L = (0, -1)

M = (0, -2)

Hence, the image of rectangle JKLM after a reflection over the y-axis around the origin is J = (6, -2), K = (6, -1), L = (0, -1) and M = (0, -2)
