Answer:
1). The correct answer is letter A)
6). The correct answer is letetr D)
Explanation:
Let be the equation of a sin function:

Where:
- A is the amplitude
- The period is 2π/B
- C is the phase shift left
- D is the vertical shift
We can see from the image of the problem (6):
The amplitude is: A = 3 units
The vertical shift is: D = 6 units
The phase shift is: C = π
The period is : P = 4π = 2π/B then B = 1/2
Therefore the correct answer is letetr D)

In the problem (1) we have:
The amplitude is: A = -2 units
The vertical shift is: D = 6 units
The phase shift is: C = π/4
The value of B = 1
Then the correct answer is letter A)
I hope it helps you!
