The value of a = 3 and b = π/6 if the innertube's height fluctuates between 2 meters and 8 meters option second is correct.
It is defined as a function which is sinusoidal in nature, and it has a domain of all real numbers and lies between the [a, a] where is a amplitude of the function.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
As we know,
-1 ≤ sinx ≤ 1
-a + 5 = 2
a = 3
12 = 2π/b
b = π/6
Thus, the value of a = 3 and b = π/6 if the innertube's height fluctuates between 2 meters and 8 meters option second is correct.
