Question

Which function has a period of 4π? y = one-half sine (one-half x) y = sine (one-fourth x) y = 2sin(2x) y = 4sin(x).

Answer 1

`\pi`Answer:

y=1/2sin(1/2 x).

Explanation:

Remember that the period is 2
`\pi`/b so the number before the x in the parentheses is b so 2
`\pi`/1/2 is 4
`\pi`. The number before sin is the amplitude, which does not matter in this problem.
