Simple...
you have:
Graph is attached.
Some ordered on this line are-->>
Using x y
(-4,-0.5)
(-3,-0.667)
(-2,-1)
(1,2)
(3,0.667)
(4,0.5)
Thus, your answer.

To sketch a given function, it is necessary that you must know it's domain first. Domain :- values of x for which function ( y) is defined. Here for x= 0, y is not defined so domain of this function is R- {0}. This graph is rectangular hyperbola. Other than this hope you are able to understand clearly... It's a bit messy.

<u><em>Answer:</em></u>
Part a .............> x = 11
Part b .............> k = 57.2
Part c .............> y = 9.2
<u><em>Explanation:</em></u>
The three problems deal with inverse variation between two variables
An inverse variation relation between two variables means that when one of the variables increases, the other will decrease (and vice versa)
<u>Mathematically, an inverse variation relation is represented as follows:</u>
where x and y are the two variables and k is the constant of variation
<u><em>Now, let's check the givens:</em></u>
<u>Part a:</u>
We are given that y = 3 and k = 33
<u>Substitute in the original relation and solve for x as follows:</u>
<u>Part b:</u>
We are given that y = 11 and x = 5.2
<u>Substitute in the original relation and solve for k as follows:</u>
<u>Part c:</u>
We are given that x=7.8 and k=72
<u>Substitute in the original relation and solve for y as follows:</u>
to the nearest tenth
Hope this helps :)
