Most of these questions can be answered by the definition of the general trigonometric functions:
y = a sin A(xφ)
a is the amplitude
2π/A = period
φ = phase shift.
If you can transform the trigonometric functions into the above form and evaluate the values of a, A, and φ, the answers would become apparent.
