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)
Answer:The required interval is (0.196, 0.030).
Step-by-step explanation:
Since we have given that
n = 432
x = 108
So,
at 99% level of confidence, z = 2.576
So, Margin of error would be
So, margin of error = 0.0536
Now, confidence interval would be
Hence, the required interval is (0.196, 0.030).
