(x^2) - 16 / x+4 = (x-4)(x+4) / (x+4) = x-4, x not equal to -4
D is the answer.
The correct equation would be Y=1/2x+4 :)
This is true because both equations have the same slope therefore they are parallel and the equation above also includes point (-6,1).
Answer:

Step-by-step explanation:
- For a horizontal compression, we multiply whole numbers greater than 1 in front of
of the given function. - For horizontal expansion, we multiply by the reciprocal of the number for horizontal compression, in front of
of the function.
For example,
If we wanted to <u>horizontally compress</u>
, we would multiply by 4 to get
, and
if we wante to <u>horizontally expand</u>
, we would multiply by
to get 
Since this question asks for horizontal compression, we multiply the
of the function by 4. So the function we need is
. The second choice is correct.
