Question 80246: i would really be thank u if u could help me out with this. thank so much
Identify the horizontal asymptotes.
f(x)=x-1/x-3
x=3
y=3
x=1
y=1
none
Question 2
Identify the vertical asymptotes.
f(x)=x-1/x-3
x=3
y=3
x=1
y=1
none
Question 3
Identify the horizontal asymptotes.
f(x)=x^2+1/x-2
x=1
y=1
x=2
y=2
none
Question 4
Identify the vertical asymptotes.
f(x)=x^2+1/x-2
x=1
y=1
x=2
y=2
none
Question 5 2 points
In the equation:
y=3x
x and y vary directly.
True
False
Question 6 Save
In the equation:
xy=0.1
x and y vary directly.
True
False
Question 7
In the equation:
y=2/x
x and y vary directly.
True
False
Question 8
If z varies jointly with the product of x and y, find the constant of variation, k, given x=1/2, y=8, z=12.
Enter only the numerical value of k.
Question 9
Using the information in question #8,
"If z varies jointly with the product of x and y, find the constant of variation, k, given x=1/2, y=8, z=12."
Write an equation that relates the variables.
Do not put any spaces between the numbers or variables in your equation.

You can put this solution on YOUR website! Identify the horizontal asymptotes.
f(x)=x-1/x-3
As x gets larger and larger f(x) gets closes and closer to x/x=1
x=1 is the horizontal asymptote.
-----------
Question 2
Identify the vertical asymptotes.
f(x)=x-1/x-3
Vertical asymptote when the denominator is zero:
x=3 is a vertical asymptote.
---------------
Question 3
Identify the horizontal asymptotes.
f(x)=x^2+1/x-2
As x get larger of larger f(x) gets closer and closer to x^2/x=x which is infinity.
So, no horizontal asymptote.
-------------
Question 4
Identify the vertical asymptotes.
f(x)=x^2+1/x-2
Denominator is zero when x=2; x=2 is the vertical asymptote.
------------
Question 5 2 points
In the equation:
y=3x
x and y vary directly.
True
Because as x gets larger y gets larger; try it and you will see.
-------------------
Question 6 Save
In the equation:
xy=0.1
x and y vary directly.
False
They vary indirectly; as x gets larger, y gets smaller so their
product will stay the same; try it.
----------------
Question 7
In the equation:
y=2/x
x and y vary directly.
False
---------------
Question 8
If z varies jointly with the product of x and y: z=k(xy)
find the constant of variation, k, given x=1/2, y=8, z=12:
12 = k(1/2*8); k=3
------------------
Question 9
Using the information in question #8,
"If z varies jointly with the product of x and y, find the constant of variation, k, given x=1/2, y=8, z=12."
k=3
