Answer:
i'm pretty sure the one you have selected in the photo is right
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
In general
Given
y = f(x) then y = f(Cx) is a horizontal stretch/ compression in the x- direction
• If C > 1 then compression
• If 0 < C < 1 then stretch
Consider corresponding points on the 2 graphs
(2, 2 ) → (4, 2 )
(4, - 2 ) → (8, - 2 )
Indicating a stretch in the x- direction.
y = f(
) with C =
, that is 0 < C < 1
stretches the graph in the x- direction by a factor of 2
Thus
y = f(
) → b
They have some of the same numbers
6 is c, i'm not entirely sure about 7
- Drive 50 miles per hour between two cities that are 200 miles apart. (200/5)
- Bicycle 30 miles at 7.5 miles per hour. (30/7.5)
