Answer:
Option b
Step-by-step explanation:
To write the searched equation we must modify the function f (x) = | x | in the following way:
1. Do y = f(x + 4)
This operation horizontally shifts the function f(x) = | x | by a factor of 4 units to the left on the x axis.
y = | x +4 |
2. Do 
This operation horizontally expands the function f (x) = | x | in a factor of 4 units. 
3. Do 
This operation vertically shifts the function f (x) = | x | by a factor of 4 units down on the y-axis.

4. After these transformations the function f(x) = | x | it looks like:

Therefore the correct option is option b. You can verify that your vertex is at point (-4, -4) by making f (-4)

A=100°
as 180-140= 40 , 40 x 2 = 80 & 180-80 = 100° = a

Step-by-step explanation:
Answer:33mph
Step-by-step explanation:
the speed decrease by 40%
Therefore, (100-40)%*55miles/h
60%*55
0.6*55
33mph
