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
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.
