The option that best describes the graphed function is: D. inverse variation; k = 4
<h3>What is an Inverse Variation?</h3>
Given two variables x and y has an inverse variation, the equation that models the relationship of the inverse variation is: y = k/x, where k = xy.
This means that as x increases, y decreases. This is the same for the graph given. So, it is an inverse variation.
When x = 2, y = 2. Therefore:
k = (2)(2)
k = 4

The value of b would be 2.5.
As you can see on the picture, the hypotenuse side goes from 8 to 16. Therefore, we know that b has to be half of 5.
I hope this helped you.

200 x 0.99. Or you can do 200/100 which is 2. then multiply that by 99 which gets you 99 which is 198.
V=448 in^3
l=8 in
w=12
h=?
V=l•w•h/3
448=8•12•h/3 multiply both sides by 3
3•448=96•h
1344=96•h
h=1344/96
h=14 in
V=l•w•h/3
h=4in
l=3in
w=2.5 in
V=?
V=4•3•2.5/3
V=30/3
V=10 in^3
The vertex of this function should be (6,-4). Since the function is in vertex form.
