Comparing to the general form of a trigonometric sine function,
The amplitude is absolute value of A
The period is given by
is a shift to the right of 4 units.
and
is an upward shift of 9 units
Therefore the phase shift is (4,9).
The correct answer is D

Answer:
5 months
Step-by-step explanation:
We assume that y represents production capacity, rather than <em>increase</em> in production capacity. Then we want to solve the 6th-degree equation ...
x^6 -25x^4 +199x^2 -4975 = 0
This can be factored in groups as ...
x^4(x^2 -25) + 199(x^2 -25) = 0
(x^4 +199)(x^2 -25) = 0
This has 4 complex solutions and 2 real solutions.
x^2 = 25
x = ±5
The duration required for capacity to reach 4975 units is 5 months.
