parent function:
Periodicity of sin (x ) is.

This is the general equation for a sinusoidal function:

determines amplitude:
or → vertical stretch
→ vertical compression
→ reflection in -axis

determines period:
or → horizontal compression by
→ horizontal stretch by
→ reflection in -axis
determines phase shift:
→ shift to the right "" units.
→ no phase shift
→ shift to the left "" units
determines vertical shift:
→ shift up "c" units
→ no vertical shift
→ shift down "" units
you are given:

so, in this case
periodicity is
=> → vertical stretch
=> → horizontal compression by
=> → shift to the right "" units
=> → shift up "" unit
