Answer: 1/2
Step-by-step explanation:
f(x) = A sin (Bx - C) + D
amplitude = |A|
period =
phase shift =
vertical shift = D
A
amplitude of 3 is given so 3 = |A| → A = ± 3, since it is stated that this is a positive function, then A = 3
B
period of 6π is given so
C
D
vertical shift of -1 is given so -1 = D
Now, substitute the values of A, B, C, and D into the formula (above):
Next, solve when x = 2π
